Abstract

This paper deals with the problem-pu+(x)|u|p-2u=(x)f(|u|) in , subjected to the zero Neumann boundary condition, where p1, N is bounded with smooth boundary, , L(), essinf0, and f:[0,+) is a not necessarily continuous nonlinearity that oscillates either at the origin or at the infinity. By using nonsmooth variational methods, we establish in both cases the existence of infinitely many distinct non-negative solutions of the Neumann problem. In our framework, : may be a sign-changing or even a nonpositive potential, which is not permitted usually in earlier works.
