Synopses & Reviews
This is a graduate text on functional analysis. After presenting the fundamental function spaces and their duals, the authors study topics in operator theory and finally develop the theory of distributions up to significant applications such as Sobolev spaces and Dirichlet problems.Along the way, the reader is presented with a truly remarkable assortment of well formulated and interesting exercises, which test the understanding as well as point out many related topics. The answers and hints that are not already contained in the statements of the exercises are collected at the end of the book.
"This book is an advanced textbook on functional analysis with an emphasis on spaces of classical and generalized functions (the book arose from a course taught for several years at the University of Evry-Val d'Essone). The basic merits of this interesting book are an elementary and transparent account of basic notations, constructions, and results of functional analysis, and a brilliant and rich set (more than 400) of well-formulated and interesting exercises. The latter not only essentially enlarge the basic contents of the book, but are a good school in functional analysis under the condition of their consecutive solving in this book one can find other remarkable results of functional analysis, which are presented with skilful pedagogical mastery. Undoubtedly, the book will be useful for researchers and lectures of functional analysis or special courses in the field as well as for students of different level which study or want to study functional analysis and its applications.
