Abstract

We consider a singularly perturbed elliptic equation

where for any The singularly perturbed problem has corresponding limiting problems

Berestycki–Lions found almost necessary and sufficient conditions on nonlinearity for existence of a solution of the limiting problem. There have been endeavors to construct solutions of the singularly perturbed problem concentrating around structurally stable critical points of potential under possibly general conditions on . In this paper, we prove that under the optimal conditions of Berestycki–Lions on , there exists a solution concentrating around topologically stable positive critical points of , whose critical values are characterized by minimax methods.
