A multiplicity result for an elliptic anisotropic differential inclusion involving variable exponents

In this paper we are concerned with the study of a class of quasilinear elliptic differential
inclusions involving the anisotropic $\overrightarrow{p}(\cdot)$-Laplace operator, on a bounded open subset of $IR^n$ which has a smooth boundary. The abstract framework required to study this kind of dierential inclusions lies at the interface of three important branches in analysis: nonsmooth analysis, the variable exponent Lebesgue-Sobolev spaces theory and the anisotropic Sobolev spaces theory. Using the concept of
nonsmooth critical point we are able to prove that our problem admits at least two non-trivial weak
solutions.
