The book is intended to be an introduction to critical point theory and its applications to differential equations. Although the related material can be found i

Many boundary value problems are equivalent to Au=O (1) where A : X --+ Y is a mapping between two Banach spaces. When the problem is variational, there exists

The book provides an introduction to minimax methods in critical point theory and shows their use in existence questions for nonlinear differential equations. A

Using minimax methods, some existence theorems are proved for critical points of a real valued function on a Banach space. The critical points are of a saddle p

The present volume contains the proceedings of the workshop on "Minimax Theory and Applications" that was held during the week 30 September - 6 October 1996 at
