QUASILINEAR ELLIPTIC SYSTEMS WITH CONVEX-CONCAVE SINGULAR TERMS AND Phi-LAPLACIAN OPERATOR

摘要

This paper deals with the existence of positive solutions for a class of quasilinear elliptic systems involving the Phi-Laplacian operator and convex-concave singular terms. Our approach is based on the generalized Galerkin Method along with perturbation techniques and comparison arguments in the setting of Orlicz-Sobolev spaces.
