Handbook of metric fixed point theory. (English) Zbl 0970.54001
Dordrecht: Kluwer Academic Publishers. xiii, 703 p. (2001).
From the preface: “Metric fixed point theory is a rather loose knit branch of fixed point theory concerning methods and results that involve properties of an essentially isometric nature. That is, the class of mappings and domains satisfying the properties need not be preserved under the move to an equivalent metric. It is this fragility that singles metric fixed point theory out from the more general topological theory, although, as many of the entries in this Handbook serve to illustrate, the divide between the two is often a vague one.”
“The focus of the book is on the major developments of the theory. Some information is put forth in detail, making clear the underlying ideas and the threads that link them. At the same time many peripheral results and extensions leading to the current state of knowledge often appear without proof and the reader is directed to primary sources elsewhere for further information. Because so many authors have been involved in this project, no effort has been made to attain a wholly uniform style or to completely avoid duplication. At the same time an attempt has been made to keep duplication to a minimum, especially where major topics are concerned.
The book begins with an overview of metric contraction principles. Then, to help delineate the theory of nonexpansive mappings and alert the reader to its subtleties, this is followed by a short chapter devoted to examples of fixed point free mappings. A survey of the classical theory of nonexpansive mappings is taken up next. After this, various topics are discussed more or less randomly, including the underlying geometric foundations of the theory in Banach spaces, ultrapower methods, stability of the fixed point property, asymptotic renorming techniques, hyperconvex spaces, holomorphic mappings, generic properties of the theory, nonlinear ergodic theory, rotative mappings, pseudocontractive mappings and local theory, the nonexpansive theory in Banach function lattices, the topological theory in a metric environment, order-theoretic aspects of the theory and set-valued mappings.”
