Infinitely many solutions via variational-hemivariational inequalities under Neumann boundary conditions

Abstract

In this article, we study the variational-hemivariational inequalities with Neumann boundary condition. Using a nonsmooth critical point theorem, we prove the existence of infinitely many solutions for boundary-value problems. Our technical approach is based on variational methods.
