Classification of Lipschitz Mappings presents a systematic, self-contained treatment of a new classification of Lipschitz mappings and its application in many topics of metric fixed point theory. Suitable for readers interested in metric fixed point theory, differential equations, and dynamical systems, the book only requires a basic background in functional analysis and topology. The author focuses on a more precise classification of Lipschitzian mappings. The mean Lipschitz condition introduced by Goebel, Japon Pineda, and Sims is relatively easy to check and turns out to satisfy several principles: Regulating the possible growth of the sequence of Lipschitz constants k(Tn) Ensuring good estimates for k0(T) and kinfinity(T) Providing some new results in metric fixed point theory "Every mathematician knows the importance of Lipschitz maps and, in particular, of the behavior of Lipschitz constants of the iterates. This book is highly recommended to anyone interested in getting insight on new developments in this area. The main part of this volume is devoted to present the basic theory of the so called 'mean Lipschitz condition,' a recent extension of the classical Lipschitz property which involves not only the property of the map itself but also of its iterates. In particular, the author present the deep influence that this condition has on the behavior of the sequence of Lipschitz constants for consecutive iterates and on its asymptotic behavior. In addition, it contains a large number of example and various applications in metric fixed point theory. The book is self-contained and addressed to advanced undergraduate and graduate students as well to researchers interested in this topic. Students will find a rich collection of examples ranging from simple to non-trivial, while specialists will be challenged by new interesting open problems." -Emanuele Casini, Dip. Scienza ed Alta Tecnologia, Insubria University "The Lipschitz condition is one of the most elegant classical concepts in mathematical analysis. It appears in university courses of differential equations and nonlinear analysis as well as in contemporary research in both pure and applied mathematics. Deep understanding of the properties of Lipschitzian mappings is therefore important for all levels of study in many branches of mathematics. This book by Lukasz Piasecki is a good choice for achieving such an understanding in the framework of mappings in general metric spaces, in particular, Banach spaces. Moreover, it gives new insight into the theory of Lipschitzian mappings via a study of the mean Lipschitz condition. This quite natural modification of the classical Lipschitz condition turns out to be very useful in the problem of estimating Lipschitz constants of the consecutive iterates of a given mapping. The author also presents its various applications to metric fixed-point theory. The book is written in a very clear and reader-friendly way. The author gives many examples illustrating various aspects of presented results. As emphasized in the introduction, the book is self-contained and only a basic knowledge of functional analysis and topology is required. It can be advised for graduate students, but specialists will also find some interesting ideas and results in it." -Stanislaw Prus, Marie Curie-Sklodowska University, Lublin, Poland "... a self-contained, readable and precise course on the subject. It is addressed to advanced undergraduate and graduate students interested in nonlinear analysis. The main stress is put on operator theory, applications to metric fixed point theory and related fields. Besides the presentation of the theory, the true value of the book lies in a collection of cleverly chosen interesting examples. As prerequisites, only a basic knowledge of functional analysis and topology is required. Students will find here materials for seminar works and presentations.
