Synopsis

This book comprehensively explores the foundations of quasiconformal mappings in the complex plane, especially in view of applications to complex dynamics. Besides playing a crucial role in dynamical systems these mappings have important applications in complex analysis, geometry, topology, potential theory and partial differential equations, functional analysis and calculus of variations, electrostatics and nonlinear elasticity . The work covers standard material suitable for a one-year graduate-level course and extends to more advanced topics, in an accessible way even for students in an initial phase of university studies who have learned the basics of complex analysis at the usual level of a rigorous first one-semester course on the subject. 

At the frontier of complex analysis with real analysis, quasiconformal mappings appeared in 1859-60 in  the cartography work of A. Tissot, well before the term “quasiconformal” was coined by L. Ahlfors in 1935. The detailed study of these mappings began in 1928 by H. Grötzsch, and L. Ahlfors’ seminal work published in 1935 significantly contributed to their development and was considered for awarding him the Fields Medal in 1936. The theory further evolved in 1937 and 1939 with O. Teichmüller’s contributions, and subsequent advancements are partially covered in this book. 

Organized into ten chapters with eight appendices, this work aims to provide an accessible, self-contained approach to the subject and includes examples  at various levels and extensive applications to holomorphic dynamics. Throughout the text, historical notes contextualize advancements over time. 

A sequel to the author’s previous book, ‘Complex Analysis and Dynamics in One Variable with Applications,’ also published by Springer, this volume might be suitable for students in mathematics, physics, or engineering. A solid background in basic mathematical analysis is recommended to fully benefit from its content.

About this title

About the Author

Luis T. Magalhães was a Professor of Mathematics at IST - Instituto Superior Técnico, University of Lisbon, Portugal, from 1993 to 2001, marking his jubilee. He obtained a degree in Electrical Engineering - Telecommunications and Electronics from IST in 1975, and earned his MSc (1980) and PhD (1982) in Applied Mathematics from Brown University, USA. Dr. Magalhães has served as President   of the Science and Technology Foundation - Portugal, the Knowledge Society Agency - Portugal, the University of Algarve General Council, the INL - International Iberian Nanotechnology Laboratory Council and the INL Installation Committee, chaired the European Union HORIZON 2020 Advisory Board on Research Infrastructures and the OECD Working Party on Measurement and Analysis of the Digital Economy, co-chaired the European Union – Africa Partnership on Science, Information Society and Space, and was a committee or council member in various organizations in Portugal and at European Union,  OECD, UN and ICANN. He was the founder and coordinator of a prominent mathematics research center, and a co-founder of the ISR - Institute of Systems and Robotics and Vice-Director of its Lisbon branch. Alongside Jack K. Hale and Waldyr M. Oliva, he co-authored the book "An Introduction to Infinite Dimensional Dynamical Systems" and authored "Complex Analysis and Dynamics in One Variable with Applications," both published by Springer. Additionally, he has authored several books in Calculus and Linear Algebra, published in Portuguese.
