Concentration Compactness: Functional-Analytic Grounds and Applications

Concentration compactness is an important method in mathematical analysis which has been widely used in mathematical research for two decades. This unique volume fulfills the need for a source book that usefully combines a concise formulation of the method, a range of important applications to variational problems, and background material concerning manifolds, non-compact transformation groups and functional spaces.

Highlighting the role in functional analysis of invariance and, in partic…
