Positive solutions for singular anisotropic $(p,q)$-equations

Analysis of PDEs 2021-01-18 v1

Abstract

In this paper we consider a Dirichlet problem driven by an anisotropic (p,q)(p,q)-differential operator and a parametric reaction having the competing effects of a singular term and of a superlinear perturbation. We prove a bifurcation-type theorem describing the changes in the set of positive solutions as the parameter moves. Moreover, we prove the existence of a minimal positive solution and determine the monotonicity and continuity properties of the minimal solution map.
