Variational Analysis and Generalized Differentiation I

Detailed Summary of the Book

This book is structured to serve both as an introduction to newcomers in the field and as an invaluable reference for seasoned researchers. It incorporates a vast array of methods, concepts, and applications, focusing on providing a rigorous exposition of variational principles tied to optimization, generalized differentiation, and nonsmooth analysis.

The main emphasis lies on developing a robust, systematic approach to generalized differentiation—a concept that extends classical calculus to nonsmooth and set-valued mappings. Concepts such as subgradients, normal cones, coderivatives, and other generalized differential constructions are meticulously explained and tied to real-world applications in optimization and variational inequalities.

The book uses exhaustive mathematical rigor to bridge the gap between theory and application, reflecting the author's expertise and dedication to the topic. It methodically explores generalized first and second-order differentiations, duality principles, and applications in problems arising in control theory, the calculus of variations, and equilibrium programming. At its core, this work aims to unify the wide array of concepts within the field and provide a clear, structured pathway for future developments.
