Abstract

In this paper, we prove a comparison principle for sub-supersolutions to a singular quasilinear problem that involves the anisotropic Finsler operator -Delta(H )(p)u := -div(Hp-1(del u) del H(del u)). As a main consequence, we obtain a uniqueness result for weak solutions to the problem (P). The proof is carried out also proving a sharp regularity result of the solutions up to the boundary. Our results are new even in the euclidean case.
