Problemas elípticos com expoente crítico e potencial de Hardy

Abstract

In this dissertation we study results of existence and non-existence for the following class of nonlinear elliptic problems: where RN denotes an open set containing the origin, bounded or not, with N > 4. The equation involves the exponent 2 = 2N/(N - 2), known as critical exponent in the Sobolev inequality, and the term mu(x)/jxj2, which is called Hardy potential. We look for solutions of the problem (P) in the Sobolev space H1 0 () which is defined as is the closure of C¥ 0 () in H1(). To obtain existence results we prove a version of theconcentration-compactness lemma by Lions.
