Variational arguments are classical techniques whose use can be traced back to the early development of the calculus of variations and further. Rooted in the physical principle of least action they have wide applications in diverse fields. This book provides a concise account of the essential tools of infinite-dimensional first-order variational analysis illustrated by applications in many areas of analysis, optimization and approximation, dynamical systems, mathematical economics and elsewhere. The book is aimed at both graduate students in the field of variational analysis and researchers who use variational techniques, or think they might like to. Large numbers of (guided) exercises are provided that either give useful generalizations of the main text or illustrate significant relationships with other results.

Editorial Reviews

From the Publisher
From the reviews:

"This book maps the progress that has been made since the publication of the Ekeland variational principle in 1974 in the development and application of the variational approach in nonlinear analysis. The authors are well equipped for their task. … This monograph is distinctive for bringing out the unifying role of variational principles across nonlinear analysis, the numerous examples of their application, and for the insights communicated by the authors, drawing on their experience as key participants in their development." (Richard B. Vinter, Mathematical Reviews, Issue 2006 h)

"The book presents a nice treatment of known variational principles and their application in many fields of mathematics. … Many exercises are provided at the end of all sections where the reader can reflect the main text and can get further generalizations of the results." (Jörg Thierfelder, Zentralblatt MATH, Vol. 1076, 2006)

"The aim of the book is to emphasize the strength of the variational techniques in various domains … . The book contains a lot of exercises completing the main text … . the book is directed to graduate students in the field of variational analysis. … Researchers who use variational techniques or intend to do so, will find the book very useful too." (S. Cobzas, Studia Universitatis Babes-Bolyai Mathematica, Vol. LI (2), June, 2006)
