摘要：
We study the regularity properties of solutions to elliptic equations similar to the p(.)-Laplacian. Our main results are a global reverse Holder inequality, Holder continuity up to the boundary and stability of solutions with respect to continuous perturbations in the variable growth exponent. We assume that the complement of the domain is uniformly fat in a capacitary sense. As technical tools, we derive a capacitary Sobolev-Poincare inequality, and a version of Hardy's inequality.
