摘要
This work is devoted to the existence and qualitative properties of ground state solutions of the Dirchlet problem for the semilinear equation -Delta u - lambda u = |u|(2)*(-2)u in a bounded domain. Here, 2* is the critical Sobolev exponent, and the term ground state refers to minimizers of the corresponding energy within the set of nontrivial solutions. We focus on the indefinite case where A is larger than the first Dirichlet eigenvalue of the Laplacian, and we present a particularly simple approach to the study of ground states.
