Abstract: In this paper we consider quasilinear hemivariational inequality at resonance. We obtain two existence theorems using a Landesman-Lazer type condition. The method of the proof is based on the nonsmooth critical point theory for locally Lipschitz functions.

Keywords: p-Laplacian, strong resonance at infinity, first eigenvalue, Clarke subdifferential, nonsmooth Palais-Smile condition, nonsmooth Cerami condition, Landesman-Lazer type conditions, mountain pass theorem.
