Existence of entropy solutions to nonlinear degenerate weighted elliptic p(.)-Laplacian problem and L1-data

Abstract

Our aim in this paper is to study the existence result of entropy solution for a specific type of nonlinear degenerate weighted elliptic  p(.)-Laplacian problems with Dirichlet-type boundary condition and  L1 data. In the framework of the theory of weighted Sobolev spaces with variable exponents, we use the regularization approach combined with a priori estimates.
