Summary

Devoted to minimax theorems and their applications to partial differential equations, this text presents these theorems in a simple and unified way, starting from a quantitative deformation lemma. Many applications are given to problems dealing with lack of compactness.

Minimax Theorems Summary

Minimax Theorems by Michel Willem

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 a differentiable functional 0 and e E X such that lIell > rand inf

Minimax Theorems Reviews

The material is presented in a unified way, and the proofs are concise and elegant... Essentially self-contained.
