Abstract

We study a class of nonlinear elliptic problems with Dirichlet conditions in the framework of the Sobolev anisotropic spaces with variable exponent, involving an anisotropic operator on an unbounded domain ΩRN (N2). We prove the existence of entropy solutions avoiding sign condition and coercivity on the lower order terms.
