Resumo

In this paper we are concerned with the study of a hemivariational
inequality with nonhomogeneous Neumann boundary condition. We
establish the existence of at least three solutions of the problem by using
the nonsmooth three critical points theorem and the principle of symmetric
criticality for Motreanu-Panagiotopoulos type functionals.
