Taschenbuch. Condition: Neu. Neuware -These notes are based on lectures presented during the seminar on ' Asymptotic Statistics' held at SchloB Reisensburg, Gunzburg, May 29-June 5, 1988. They consist of two parts, the theory of asymptotic expansions in statistics and probabilistic aspects of the asymptotic distribution theory in nonparametric statistics. Our intention is to provide a comprehensive presentation of these two subjects, leading from elementary facts to the advanced theory and recent results. Prospects for further research are also included. We would like to thank all participants for their stimulating discussions and their interest in the subjects, which made lecturing very pleasant. Special thanks are due H. Zimmer for her excellent typing. We would also like to take this opportunity to to express our thanks to the Gesellschaft fur mathematische Forschung and to the Deutsche Mathematiker Vereinigung, especially to Professor G. Fischer, for the opportunity to present these lectures and to the Birkhauser Verlag for the publication of these lecture notes. R. Bhattacharya, M.

Taschenbuch. Condition: Neu. Neuware -Kurt Gödel, together with Bertrand Russell, is the most important name in logic, and in the foundations and philosophy of mathematics of this century. However, unlike Russel, Gödel the mathematician published very little apart from his well-known writings in logic, metamathematics and set theory. Fortunately, Gödel the philosopher, who devoted more years of his life to philosophy than to technical investigation, wrote hundreds of pages on the philosophy of mathematics, as well as on other fields of philosophy. It was only possible to learn more about his philosophical works after the opening of his literary estate at Princeton a decade ago. The goal of this book is to make available to the scholarly public solid reconstructions and editions of two of the most important essays which Gödel wrote on the philosophy of mathematics. The book is divided into two parts. The first provides the reader with an incisive historico-philosophical introduction to Gödel's technical results and philosophical ideas. Written by the Editor, this introductory apparatus is not only devoted to the manuscripts themselves but also to the philosophical context in which they were written. The second contains two of Gödel's most important and fascinating unpublished essays: 1) the Gibbs Lecture ('Some basic theorems on the foundations of mathematics and their philosophical implications', 1951); and 2) two of the six versions of the essay which Gödel wrote for the Carnap volume of the Schilpp series The Library of Living Philosophers ('Is mathematics syntax of language ', 1953-1959).Springer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 240 pp. Englisch.

Taschenbuch. Condition: Neu. Neuware -Structural properties play an important role in our understanding of linear systems in the state space representation. The structural canonical form representation of linear systems not only reveals the structural properties but also facilitates the design of feedback laws that meet various control objectives. In particular, it decomposes the system into various subsystems. These subsystems, along with the interconnections that exist among them, clearly show the structural properties of the system. The simplicity of the subsystems and their explicit interconnections with each other lead us to a deeper insight into how feedback control would take effect on the system, and thus to the explicit construction of feedback laws that meet our design specifications. The discovery of structural canonical forms and their applications in feedback design for various performance specifications has been an active area of research for a long time. The effectiveness of the structural decomposition approach has also been extensively explored in nonlinear systems and control theory in the recent past. The aim of this book is to systematically present various canonical represen tations of the linear system, that explicitly reveal different structural properties of the system, and to report on some recent developments on its utilization in sys tem analysis and design.Springer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 436 pp. Englisch.

Taschenbuch. Condition: Neu. Neuware -To commemorate properly the 70th birthday of a man who, by his very nature, is too busy to pause for any kind of ceremonial event unless it has a concomitant functional output was a difficult problem for the Staff and Associates of the Neurosciences Research Program. Frank (F. O. S. ) has always dreaded the prospect that sometime it might be appropriate for his colleagues to present him a Fest schrift. In fact, 'Fest me no Schriften' became his battle cry, expressing his feeling that the idea of testimonials clustered into a book was anathema. So the 'break through' idea for the planners was to organize a symposium around the theme of discovery in neuroscience that would be valuable scientifically and, in its demon stration of interdisciplinary interaction, would support that emphasis in Frank's career. After much planning a program was developed, beginning with a birthday party the evening before, followed by the two-day symposium, and closing with the first F. O. Schmitt Lecture in Neuroscience. We hope that publication of the scientific proceedings in this volume will be of interest not only to the neuroscience community, but also to a broad general readership interested in discovery, under standing, and the creative processes in scientific work. An organizing committee, chaired by Fred Worden, collected advice and guidance leading to the selection of speakers whose scientific careers have played an important part in the recent history of modern neuroscience.Springer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 648 pp. Englisch.

Taschenbuch. Condition: Neu. Neuware - This is a book about isomorphisms 0/ types, arecent difficult research topic in type theory that turned out to be able to have valuable practical applications both for programming language design and far more human centered information retrieval in software libraries. By means of a deep study of the syntax of the now widely known typed A-ca1culus, it is possible to identify some simple equations between types that on one hand allow to improve the design of the ML language, and on the other hand provide the basis for building radically new information retrieval systems for functional software libraries. We present in this book both the theoretical aspects of these researches and a fully functional implementation of some of their applications in such a way to provide interesting material both for the theoretician looking for proofs and for the practitioner interested in implementation details. In order to make it possible for these different types of readers to use this book effectively, some special signs are used to designate material that is particularly technical or applied or that represents a digression. When the symbol appears at the beginning of a section or a subsection, it warns that the material contained in such section is particularly technical with respect to the general level of the chapter or section where it is located. This material is generally reserved to theoreticians and does not need to be read by the casual reader.

Buch. Condition: Neu. Neuware -This second edition of Mathematical Olympiad Treasures contains a stimulating collection of problems in geometry and trigonometry, algebra, number theory, and combinatorics. It encourages readers to think creatively about techniques and strategies for solving real-world problems, with new sections, revisions, and many more Olympiad-like problems at various levels of difficulty.The problems are clustered by topic into three self-contained chapters. The book begins with elementary facts, followed by carefully selected problems and detailed, step-by-step solutions, which then lead to more complicated, challenging problems and their solutions. Reflecting the vast experience of two professors andMathematical Olympiad coaches, the text will be invaluable to teachers, students, and puzzle enthusiasts. The advanced reader is challenged to find alternative solutions and extensions of the proposed problems.Springer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 264 pp. Englisch.

Taschenbuch. Condition: Neu. Neuware -17 2 STRESS FIELDS FOR SIMPLE STRUCTURES 2. 1 INTRODUCTION In this chapter the behavior and strength of simple structures made of rein forced or prestressed concrete is investigated with the aid of stress fields. In particular, the webs and flanges of beams, simple walls, brackets, bracing beams and joints of frames are investigated. By this means, the majority of design cases are already covered. In reality, all structural components are three-dimensional. Here, however, components are considered either directly as two-dimensional plate elements (i. e. the plane stress condition with no variation of stress over the thickness of the element) or they are subdivided into several plates. Since two-dimensional structural elements are statically redundant, it is pOSSible for a particular loading to be in equilibrium with many (theoretically an infinite number of) stress states. If the lower bound method of the theory of plasticity is employed, then an admissible stress field or any combination of such stress fields may be selected. In chapter 4 it is shown that this method is suitable for the design of reinforced concrete structures, and the consequence of the choice of the final structural system on the structural behavior is dealt with in detail. The first cases of the use of this method date back to Ritter [6] and Morsch [4], who already at the beginning of the century investigated the resultants of the internal stresses by means of truss models.Springer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 160 pp. Englisch.

Taschenbuch. Condition: Neu. Neuware -These volumes are companions to the treatise; 'Fundamentals of the Theory of Operator Algebras,' which appeared as Volume 100 - I and II in the series, Pure and Applied Mathematics, published by Academic Press in 1983 and 1986, respectively. As stated in the preface to those volumes, 'Their primary goal is to teach the sub ject and lead the reader to the point where the vast recent research literature, both in the subject proper and in its many applications, becomes accessible.' No attempt was made to be encyclopCEdic; the choice of material was made from among the fundamentals of what may be called the 'classical' theory of operator algebras. By way of supplementing the topics selected for presentation in 'Fundamentals,' a substantial list of exercises comprises the last section of each chapter. An equally important purpose of those exer cises is to develop 'hand-on' skills in use of the techniques appearing in the text. As a consequence, each exercise was carefully designed to depend only on the material that precedes it, and separated into segments each of which is realistically capable of solution by an at tentive, diligent, well-motivated reader.Springer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 292 pp. Englisch.

Buch. Condition: Neu. Neuware -The book consists of solicited articles from a select group of mathematicians and physicists working at the interface between positivity andthe geometry, combinatorics or analysis of polynomials of one or several variables. It is dedicated to the memory of Julius Borcea (1968-2009), a distinguished mathematician, Professor at the University of Stockholm. With his extremely original contributions and broad vision, his impact on the topics of the planned volume cannot be underestimated. All contributors knew or have exchanged ideas with Dr. Borcea, and their articles reflect, at least partially, his heritage.Springer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 424 pp. Englisch.

Buch. Condition: Neu. Neuware -Urban subsurface resources and particularly urban groundwater are vulnerable to environmental impacts, and their rational management is of major importance. In this book a multidisciplinary team of specialists and scientists presents innovative process-oriented approaches to the sustainable use of these resources. The included case studies from northwestern Switzerland describe representative environments and are relevant for urban areas in general. They illustrate the protection of groundwater; river restoration; engineering and hydrogeological questions related to urban infrastructure and management concepts; as well as monitoring, modeling and remediation strategies for contaminated sites; problems caused by karst in urban environments; the use of shallow geothermal energy; and natural hazards such as flood events and earthquakes.It is demonstrated that modern quantitative earth sciences can contribute significantly in finding solutions concerning the sustainable use of subsurface resources in urban environments.The book is an invaluable source of information for hydrogeologists, geologists, urban planners, water supply engineers, and environmental agencies.Springer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 232 pp. Englisch.

Taschenbuch. Condition: Neu. Neuware -Two events have recently improved the prospects of protecting fish and their environment in Switzerland: the acceptance of a new Federal Water Protection Law in the plebiscite of May 17th 1992, and the new Federal Legislation on Fisheries, in force since January 1st 1994. With this legal framework, the possibilities for protection of nature and landscape have now considerably improved in Switzerland. The most important aims of the Federal Law on Water Protection are to safeguard the natural habitats of the native flora and fauna and water as the habitat of aquatic organisms. This includes not only the preservation or restoration of water quality in lakes and rivers, but also, in rivers used for hydroelectricity, irrigation or as industrial or other water supplies, the maintenance of sufficient water to fulfill the minimal requirements for fish. However, good quality water in sufficient quan tities alone is not enough to guarantee the survival of fish. Intact fish habitats comprise various phYsical structures including plenty of hiding places, hunting grounds, reproduction and nursery areas within suitable distances from each other. This third aspect of conservation and restoration of aquatic habitats is a central point in the new Federal Law on Fisheries. Whereas the former versions of this law were more concerned with fishery regulations, the recent legislation defines new areas of responsibility for the federal and the cantonal governments.Springer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 360 pp. Englisch.

Taschenbuch. Condition: Neu. Neuware -Gian-Carlo Rota was born in Vigevano, Italy, in 1932. He died in Cambridge, Mas sachusetts, in 1999. He had several careers, most notably as a mathematician, but also as a philosopher and a consultant to the United States government. His mathe matical career was equally varied. His early mathematical studies were at Princeton (1950 to 1953) and Yale (1953 to 1956). In 1956, he completed his doctoral thesis under the direction of Jacob T. Schwartz. This thesis was published as the pa per 'Extension theory of differential operators I', the first paper reprinted in this volume. Rota's early work was in analysis, more specifically, in operator theory, differ ential equations, ergodic theory, and probability theory. In the 1960's, Rota was motivated by problems in fluctuation theory to study some operator identities of Glen Baxter (see [7]). Together with other problems in probability theory, this led Rota to study combinatorics. His series of papers, 'On the foundations of combi natorial theory', led to a fundamental re-evaluation of the subject. Later, in the 1990's, Rota returned to some of the problems in analysis and probability theory which motivated his work in combinatorics. This was his intention all along, and his early death robbed mathematics of his unique perspective on linkages between the discrete and the continuous. Glimpses of his new research programs can be found in [2,3,6,9,10].Springer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 416 pp. Englisch.

Taschenbuch. Condition: Neu. Neuware -For textual studies relating to the ancient mathematical corpus the efforts by the Danish philologist, 1. L. Heiberg (1854-1928), are especially significant. Beginning with his doctoral dissertation, Quaestiones Archimedeae (Copen hagen, 1879), Heiberg produced an astonishing series of editions and critical studies that remain the foundation of scholarship on Greek mathematical 4 science. For comprehensiveness and accuracy, his editions are exemplary. In his textual studies, as also in the prolegomena to his editions, he carefully described the extant evidence, organized the manuscripts into stemmata, and drew out the implications for the state of the text. 5 With regard to his Archimedean work, Heiberg sometimes betrayed signs of the philologist's occupational disease - the tendency to rewrite a text deemed on subjective grounds to be unworthy. 6 But he did so less often than his prominent 7 contemporaries, and not as to detract appreciably from the value of his editions. In examining textual questions bearing on the Archimedean corpus, he attempted to exploit as much as possible evidence from the ancient commentators, and in some instances from the medieval translations. It is here that opportunities abound for new work, extending, and in some instances superseding, Heiberg's findings. For at his time the availability of the medieval materials was limited. In recent years Marshall Clagett has completed a mammoth critical edition of the medieval Latin tradition of Archimedes,8 while the bibliographical instruments for the Arabic tradition are in good order thanks to the work of Fuat Sezgin.Springer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 876 pp. Englisch.

Taschenbuch. Condition: Neu. Neuware -The work of Hans Lewy (1904--1988) has had a profound influence inthe direction of applied mathematics and partial differentialequations, in particular, from the late 1920s. Two of the particularsare well known. The Courant--Friedrichs--Lewy condition (1928), or CFLcondition, was devised to obtain existence and approximation results.This condition, relating the time and spatial discretizations forfinite difference schemes, is now universally employed in thesimulation of solutions of equations describing propagation phenomena.Lewy's example of a linear equation with no solution (1957), with itsattendant consequence that most equations have no solution, was notmerely an unexpected fact, but changed the viewpoint of the entirefield.Lewy made pivotal contributions in many other areas, for examplethe regularity theory of elliptic equations and systems, the MongeAmpSre Equation, the Minkowski Problem, the asymptotic analysis ofboundary value problems, and several complex variables. He was amongthe first to study variational inequalities. In much of his work, hisunderlying philosophy was that simple tools of function theory couldhelp one understand the essential concepts embedded in an issuealthough at a cost in generality. This approach was extremelysuccessful.In this two-volume work, most all of Lewy's papers are presentedin chronological order. They are preceded by several short essaysabout Lewy himself, prepared by Helen Lewy, Constance Reid, and DavidKinderlehrer, and commentaries on his work by Erhard Heinz, Peter LaxJean Leray, Richard MacCamy, Fran ois Treves, and Louis Nirenberg.Additionally, there are Lewy's own remarks on the occasion of hishonorary degree from the University of Bonn.Springer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 468 pp. Englisch.

Taschenbuch. Condition: Neu. Neuware -The theory of integral equations has been an active research field for many years and is based on analysis, function theory, and functional analysis. On the other hand, integral equations are of practical interest because of the «boundary integral equation method», which transforms partial differential equations on a domain into integral equations over its boundary. This book grew out of a series of lectures given by the author at the Ruhr-Universitat Bochum and the Christian-Albrecht-Universitat zu Kiel to students of mathematics. The contents of the first six chapters correspond to an intensive lecture course of four hours per week for a semester. Readers of the book require background from analysis and the foundations of numeri cal mathematics. Knowledge of functional analysis is helpful, but to begin with some basic facts about Banach and Hilbert spaces are sufficient. The theoretical part of this book is reduced to a minimum; in Chapters 2, 4, and 5 more importance is attached to the numerical treatment of the integral equations than to their theory. Important parts of functional analysis (e. g. , the Riesz-Schauder theory) are presented without proof. We expect the reader either to be already familiar with functional analysis or to become motivated by the practical examples given here to read a book about this topic. We recall that also from a historical point of view, functional analysis was initially stimulated by the investigation of integral equations.Springer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 380 pp. Englisch.

Taschenbuch. Condition: Neu. Neuware -The theory of vertex operator algebras and their representations has been showing its power in the solution of concrete mathematical problems and in the understanding of conceptual but subtle mathematical and physical struc tures of conformal field theories. Much of the recent progress has deep connec tions with complex analysis and conformal geometry. Future developments, especially constructions and studies of higher-genus theories, will need a solid geometric theory of vertex operator algebras. Back in 1986, Manin already observed in [Man) that the quantum theory of (super )strings existed (in some sense) in two entirely different mathematical fields. Under canonical quantization this theory appeared to a mathematician as the representation theories of the Heisenberg, Vir as oro and affine Kac Moody algebras and their superextensions. Quantization with the help of the Polyakov path integral led on the other hand to the analytic theory of algebraic (super ) curves and their moduli spaces, to invariants of the type of the analytic curvature, and so on. He pointed out further that establishing direct mathematical connections between these two forms of a single theory was a 'big and important problem. ' On the one hand, the theory of vertex operator algebras and their repre sentations unifies (and considerably extends) the representation theories of the Heisenberg, Virasoro and Kac-Moody algebras and their superextensions.Springer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 300 pp. Englisch.

Taschenbuch. Condition: Neu. Neuware -Ernst Specker has made decisive contributions towards shaping direc tions in topology, algebra, mathematical logic, combinatorics and algorith mic over the last 40 years. We have derived great pleasure from marking his seventieth birthday by editing the majority of his scientific publications, and thus making his work available in a unified form to the mathematical community. In order to convey an idea of the richness of his personality, we have also included one of his sermons. Of course, the publication of these Selecta can pay tribute only to the writings of Ernst Specker. It cannot adequately express his originality and wisdom as a person nor the fascination he exercises over his students, colleagues and friends. We can do no better than to quote from Hao Wang in the 'Festschrift' Logic and Algorithmic I: Specker was ill for an extended period before completing his formal education. He had the leisure to think over many things. This experi ence may have helped cultivating his superiority as a person. In terms of traditional Chinese categories, I would say there is a taoist trait in him in the sense of being more detached, less competitive, and more under standing. I believe he has a better sense of what is important in life and arranges his life better than most logicians. We are grateful to Birkhauser Verlag for the production of this Selecta volume. Our special thanks go to Jonas Meon for sharing with us his intimate knowledge of his friend Ernst Specker.Springer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 432 pp. Englisch.

Taschenbuch. Condition: Neu. Neuware -The field of neuroscience is experiencing a period of unprecedented growth. The range of ap proaches used to investigate the fundamental mechanisms underlying different aspects of somatosen sory perception has expanded substantially since the last International Symposium on Informa tion Processing in the Somatosensory System. Diversity of approach has become the hallmark of somatosensory research, and I believe that the impact of this diversity continues to be positive. of this symposium with previous symposia will show that researchers are employing Comparison an array of new methods and technologies and that they are offering new insights into old ques tions. The techniques range from studies of ionic channels, single unit recordings, functional brain imaging to psychophysics. A careful reading ofthe chapters reveals subtle and, on occasion, also obvious differences of opinion about experimental outcomes, approaches, and views. These differences are healthy signs of venture into new and uncharted territories. It is my hope that read ers will appreciate both the diversity of the research addressing somesthesis, and the personal commitment, enthusiasm, and scientific rigor of the participants who made this symposium and volume meaningful for all involved. We all look forward to tracking the progress of somatosensory research at our next Symposium at the turn of the century. OveFranzen November 1995 xv List of Contributors David T.

Taschenbuch. Condition: Neu. Neuware -Harmonic maps are solutions to a natural geometrical variational prob lem. This notion grew out of essential notions in differential geometry, such as geodesics, minimal surfaces and harmonic functions. Harmonic maps are also closely related to holomorphic maps in several complex variables, to the theory of stochastic processes, to nonlinear field theory in theoretical physics, and to the theory of liquid crystals in materials science. During the past thirty years this subject has been developed extensively. The monograph is by no means intended to give a complete description of the theory of harmonic maps. For example, the book excludes a large part of the theory of harmonic maps from 2-dimensional domains, where the methods are quite different from those discussed here. The first chapter consists of introductory material. Several equivalent definitions of harmonic maps are described, and interesting examples are presented. Various important properties and formulas are derived. Among them are Bochner-type formula for the energy density and the second varia tional formula. This chapter serves not only as a basis for the later chapters, but also as a brief introduction to the theory. Chapter 2 is devoted to the conservation law of harmonic maps. Em phasis is placed on applications of conservation law to the mono tonicity formula and Liouville-type theorems.Springer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 260 pp. Englisch.

Taschenbuch. Condition: Neu. Neuware -This book was written to make the material presented in my book, Stahlbetonbrucken, accessible to a larger number of engineers throughout the world. A work in English, the logical choice for this task, had been contemplated as Stahlbetonbrucken was still in its earliest stages of preparation. The early success of Stahlbetonbrucken provided significant impetus for the writing of Prestressed Concrete Bridges, which began soon after the publication of its predecessor. The present work is more than a mere translation of Stahlbetonbrucken. Errors in Stahlbetonbrucken that were detected after publication have been corrected. New material on the relation between cracking in concrete and corrosion of reinforce ment, prestressing with unbonded tendons, skew-girder bridges, and cable-stayed bridges has been added. Most importantly, however, the presentation of the material has been extensively reworked to improve clarity and consistency. Prestressed Concrete Bridges can thus be regarded as a thoroughly new and improved edition of its predecessor.Springer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 552 pp. Englisch.

Buch. Condition: Neu. Neuware -Influenza continues to be an ongoing problem despite the existence of vaccines and drugs. Disease outbreaks can occur relatively quickly as witnessed with the recent emergence of the influenza virus A/H1N1 pandemic. The development of new anti-influenza drugs is thus a major challenge.This volume describes all aspects of the virus structure and function relevant to infection. The focus is on drug discovery of inhibitors to the enzyme sialidase, which plays a key role in the infectious lifecycle of the virus. Following an overview of the influenza virus, the haemagglutinin, the interactions with the cell receptors and the enzymology of virus sialidase, recent results in drug design are presented. These include a full coverage of the design, synthesis and evaluation of carbohydrate as well as non-carbohydrate influenza virus sialidase inhibitors. Further reviews of the clinical experience with influenza virus sialidase inhibitors and of the development of resistance to these inhibitor drugs complement the topic.Springer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 188 pp. Englisch.

Taschenbuch. Condition: Neu. Neuware -Der heutige Hochschulunterricht für Mathematiker gründet meist auf Abstraktion und führt vom Allgemeinen zum Speziellen. Die Methode hat Vorteile, sie stärkt das Denkvermögen und meidet lästige Wiederholungen. Doch sie 'stellt den Pflug vor die Ochsen', weil Abstraktion auf Spezialfälle baut, die dem Lernenden oft fremd sind. So bleibt der Erfolg den Glücklichen vorbehalten, die den Weg von der Abstraktion zu den Beispielen finden. Dieses Lehrbuch führt von zwei Spezialfällen zur Allgemeinheit und gründet nicht auf Abstraktion. Die Beweise der abstrakten Algebra werden zuerst am konkreten Beispiel der Matrizen vorgeführt. Zur Schärfung der Anschauung wird dann die Begriffswelt der Elementargeometrie durchleuchtet. Die Auseinandersetzung mit dem Lehrstoff der Schule dient der Vorbereitung auf die geometrisch gefärbte Sprache der linearen Algebra, die am Ende des Buches erläutert wird. Dem Text sind Anwendungsbeispiele und zahlreiche historische Kommentare beigefügt.Springer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 652 pp. Deutsch.

Taschenbuch. Condition: Neu. Neuware -Der Astronom F.W. Bessel gilt zusammen mit dem Mathematiker C.G.J. Jacobi und dem Physiker Franz Neumann als Begründer der sogenannten 'Königsberger Schule', die auf die Universitäten in Deutsch- land, aber auch in Russland und im gesamten osteuropäischen Raum, einen grossen Einfluss hatte. Als Autodidakt erwarb sich Bessel schon in jungen Jahren mit seinen astronomischen Arbeiten die Anerkennung der führenden Gelehrten seiner Zeit. Nachdem er als Professor an die Albertina nach Königsberg berufen worden war, erhielt er bereits mit 27 Jahren auf Betreiben von Gauss die Ehren- doktorwürde der Universität Göttingen. Ihm wurde die Planung und der Bau der Königsberger Sternwarte übertragen, die sich unter seiner Leitung zu einem internationalen Zentrum der Astronomie entwickelte. Bessel leistete aber nicht nur in der Astronomie und der Geodäsie Bedeutendes, sondern auch in der Theoretischen Mathematik. Diese Biographie beschränkt sich nicht auf die Schilderung der wissenschaftlichen Leistungen Bessels, sondern stellt ihn auch als Mensch und Persönlichkeit vor. Besondere Aufmerksamkeit widmet das Buch den engen wissenschaftlichen und persönlichen Be- ziehungen, die Bessel, nachdem er schon in jungen Jahren in die Petersburger Akademie aufgenommen worden war, zur russischen Wissenschaft und zu den russischen Wissenschaftlern entwickelt hat. Engagiert und lebendig schildert der Autor Bessels Lebensgeschichte und versucht, Bessels zahlreiche, weitgespannte wissenschaftliche Arbeiten und Leistungen auch dem Nichtfachmann verständlich und spannend darzustellen.Springer Basel AG in Springer Science + Business Media, Heidelberger Platz 3, 14197 Berlin 332 pp. Deutsch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -A number of years ago, Harriet Sheridan, then Dean of Brown University, organized a series oflectures in which individual faculty members described how it came about that they entered their various fields. I was invited to participate in this series and found in the invitation an opportunity to recall events going back to my early teens. The lecture was well received and its reception encouraged me to work up an expanded version. My manuscript lay dormant all these years. In the meanwhile, sufficiently many other mathematical experiences and encounters accumulated to make this little book. My 1981 lecture is the basis of the first piece: 'Napoleon's Theorem. ' Although there is a connection between the first piece and the second, the four pieces here are essentially independent. The sec ond piece, 'Carpenter and the Napoleon Ascription,' has as its object a full description of a certain type of scholar-storyteller (of whom I have known and admired several). It is a pastiche, contain ing a salad bar selection blended together by my own imagination. This piece purports, as a secondary goal, to present a solution to a certain unsolved historical problem raised in the first piece. The third piece, 'The Man Who Began His Lectures with 'Namely',' is a short reminiscence of Stefan Bergman, one of my teachers of graduate mathematics. Bergman, a remarkable person ality, was born in Poland and came to the United States in 1939. 316 pp. Englisch.

Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Entre Meeanique et Arehiteeture: e'est-a-dire, entre les proeedes teehniques qui, depuis des temps immemoriaux eonforment l'art et la scienee de la eonstruetion au developpement de la scienee physique et mathematique la plus generale et, peut-etre, la plus abstraite, subalternata tanturn geometriae et philosophiae naturalis, eomme le disait Tartaglia, bien que liee aux faits les plus farniliers: la statique et la meeanique des mareriaux et des struetures. Le theme qui nous eoneeme est done la relation entre la technique et la scienee dans son exemple le plus important, je crois, du point de vue historiographique mais aussi epistemologique: a savoir, la relation entre le savoir faire, qui se eonforme a la norme, en respeetant une determination et une eongruenee parfaites avee son objectif, et la theorie, qui eonfirme la norme et temoigne la neeessite de la determiner eongrfiment avec les lois de la nature. Avee une extreme perspieaeite, quelque peu offusquee par une frivolite erudite, l' Abbe Franeeseo Maria Franeesehinis, mathematieien et adepte de la philosophie des lurnieres, se peneha sur la question dans un bref traite qu'il publia a Padoue en 1808 sous 1 le titre Des Mathematiques appliquees , soutenant la nouvelle tendanee didaetique introduite a l'Universite de Padoue par l'ephemere Regne d'Italie. Simulant un eonflit entre plusieurs auteurs, Franeesehinis exposait une premiere these dans un Discours inaugural qu'il reeita peut-etre reellement en 1807, lorsqu'il devint titulaire de la Chaire de Mathematiques appliquees. 408 pp. Englisch.
