Abstract:
In this article, we study a pseudo-differential inclusion driven by a nonlocal
anisotropic operator and a Clarke generalized subdifferential of a nonsmooth
potential, which satisfies nonresonance conditions both at the origin and at
infinity. We prove the existence of three nontrivial solutions: one positive,
one negative and one of unknown sign, using variational methods based on
nosmooth critical point theory, more precisely applying the second
deformation theorem and spectral theory. Here, a nosmooth anisotropic version
of the Holder versus Sobolev minimizers relation play an important role.
