On some elliptic hemivariational and variational–hemivaritional inequalities Original Research Article

The existence of solutions to an elliptic hemivariational inequality involving the pp-Laplacian is first established. The variational–hemivariational case, which includes the above one, is then examined when p=2p=2. Both of them are chiefly treated through Mountain Pass like critical point results for non-differentiable functions.
