Synopsis

Lectori salutem! The kind reader opens the book that its authors would have liked to read it themselves, but it was not written yet. Then, their only choice was to write this book, to fill a gap in the mathematicalliterature. The idea of convexity has appeared in the human mind since the antiquity and its fertility has led to a huge diversity of notions and of applications. A student intending a thoroughgoing study of convexity has the sensation of swimming into an ocean. It is due to two reasons: the first one is the great number of properties and applications of the classical convexity and second one is the great number of generalisations for various purposes. As a consequence, a tendency of writing huge books guiding the reader in convexity appeared during the last twenty years (for example, the books of P. M. Gruber and J. M. Willis (1993) and R. J. Webster (1994)). Another last years' tendency is to order, from some point of view, as many convexity notions as possible (for example, the book of I. Singer (1997)). These approaches to the domain of convexity follow the previous point of view of axiomatizing it (A. Ghika (1955), W. Prenowitz (1961), D. Voiculescu (1967), V. W. Bryant and R. J. Webster (1969)). Following this last tendency, our book proposes to the reader two classifications of convexity properties for sets, both of them starting from the internal mechanism of defining them.

About this title

Synopsis

The notion of convex set, known according to its numerous applications in linear spaces due to its connectivity which leads to separation and support properties, does not imply, in fact, necessarily, the connectivity. This aspect of non-connectivity hidden under the convexity is discussed in this book. The property of non-preserving the connectivity leads to a huge extent of the domain of convexity. The book contains the classification of 100 notions of convexity, using a generalised convexity notion, which is the classifier, ordering the domain of concepts of convex sets.Also, it opens the wide range of applications of convexity in non-connected environment. Applications in pattern recognition, in discrete programming, with practical applications in pharmaco-economics are discussed. Both the synthesis part and the applied part make the book useful for more levels of readers. It is suitable for researchers dealing with convexity and related topics, young researchers at the beginning of their approach to convexity, PhD and master students.
