Nodal and constant sign solutions for singular elliptic problems

Analysis of PDEs 2023-10-30 v1

Abstract

We establish the existence of multiple solutions for singular quasilinear elliptic problems with a precise sign information: two opposite constant sign solutions and a nodal solution. The approach combines sub-supersolutions method and Leray-Schauder topological degree involving perturbation argument.
