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 $\varOmega \subset \mathbb{R}^{N}$ $(N \geq 2)$. We prove the existence of entropy solutions avoiding sign condition and coercivity on the lower order terms.
