Multiplicity of positive solutions for nonlinear field equations in
arXiv:0901.4459
Abstract
In this paper we study the multiplicity of positive solutions for nonlinear elliptic equations on . The number of solutions is greater or equal than the number of disjoint intervals on which the nonlinear term is negative. Applications are given to multiplicity of standing waves for the nonlinear Schrödinger and Klein-Gordon equations.
