The aim of this volume is to make available to a large audience recent
material in nonlinear functional analysis that has not been covered in
book format before. Here, several topics of current and growing interest
are systematically presented, such as fixed point theory, best
approximation, the KKM-map principle, and results related to
optimization theory, variational inequalities and complementarity
problems. Illustrations of suitable applications are given, the links
between results in various fields of research are highlighted, and an
up-to-date bibliography is included to assist readers in further
studies.
Audience: This book will be of interest to graduate students,
researchers and applied mathematicians working in nonlinear functional
analysis, operator theory, approximations and expansions, convex sets
and related geometric topics and game theory
