Introduction to Nonlinear Functional Analysis and Elliptic Problems

Both authors are leading experts in this area of mathematics. Antonio Ambrosetti has been at the very forefront of research in this field for forty years, and several of the major topics from Parts 1 and 2 of the book are drawn from his research.

From the reviews: "The book is devoted to nonlinear functional analysis and its applications to semilinear elliptic boundary value problems. It covers a great variety of topics and gives a good introduction to the subject. ... The book is aimed at graduate and senior undergraduate students." (Alexander A. Pankov, Mathematical Reviews, Issue 2012 f) "This book provides some basic abstract tools used in modern nonlinear analysis in strong relationship with their applications to semilinear elliptic boundary value problems. ... This monograph is suitable for graduate students and researchers ... . the volume under review should certainly be in the library of every university where research in mathematics is conducted." (Vicentiu D. Radulescu, Zentralblatt MATH, Vol. 1228, 2012)
