摘要:

We study a nonlinear periodic problem driven by the p(t)-Laplacian and hav-ing a nonsmooth potential (hemivariational inequalities). Using a variational method based on nonsmooth critical point theory for locally Lipschitz functions, we first prove the exis-tence of at least two nontrivial solutions under the generalized subquadratic and then estab-lish the existence of at least one nontrivial solution under the generalized superquadratic.

关键词: p(t)-Laplacian, periodic solution, variable exponent Sobolev space, minimax principle, generalized subdifferential, local linking reduction method
