Positive solutions for singular double phase problems

Analysis of PDEs 2021-05-17 v1

Abstract

We study the existence of positive solutions for a class of double phase Dirichlet equations which have the combined effects of a singular term and of a parametric superlinear term. The differential operator of the equation is the sum of a pp-Laplacian and of a weighted qq-Laplacian (q<pq<p) with discontinuous weight. Using the Nehari method, we show that for all small values of the parameter λ>0\lambda>0, the equation has at least two positive solutions.
