Existence of Two Nontrivial Solutions for Semilinear Elliptic Problems

Abstract

This paper concerns the existence of multiple nontrivial solutions for some nonlinear problems. The first nontrivial solution is found using a minimax method, and the second by computing the Leray-Schauder index and the critical group near 0.
