Resumen de Existence of Positive Solutions for Nonlinear Noncoercive Hemivariational Inequalities

Michael E. Filippakis, Nikolaos S. Papageorgiou

• In this paper we investigate the existence of positive solutions for nonlinear elliptic problems driven by the p-Laplacian with a nonsmooth potential (hemivariational inequality). Under asymptotic conditions that make the Euler functional indefinite and incorporate in our framework the asymptotically linear problems, using a variational approach based on nonsmooth critical point theory, we obtain positive smooth solutions. Our analysis also leads naturally to multiplicity results.
