Nonlinear Analysis

“This volume focuses on topics of nonlinear analysis related to the analysis of boundary value problems, control theory and the calculus of variations. It is mostly self-contained and, at the same time, it contains an impressive amount of material organized in 7 chapters – each of which, without being exhaustive, surveys and area of nonlinear analysis, starting with a brief introduction and finishing with historical comments. At the end of the book, there is an appendix containing basic results on topology, measure theory and functional analysis. Each chapter, which could have been a book by its own, moves rapidly from elementary definitions to involved results and generally presumes a degree of familiarity with the subject or requires a certain level of mathematical maturity. … this volume can be highly appreciated by readers without a pure theoretical background and orientation. Here on can find results previously contained only in scattered papers, not always easily accessible. … The reader might also find extremely useful the index table at the end … It may serve as a valuable reference text for active researchers in the area of nonlinear analysis and/or partial differential equations treated with variational techniques.”

“The text is clearly and , in general, carefully written. This book is useful for researchers and parts of it can be recommended as additional reading for postgraduate students.”
