On the Elliptic Problems Involving Multisingular Inverse Square Potentials and Concave-Convex Nonlinearities

Abstract

A semilinear elliptic problem $\left(E_{\lambda }\right)$ with concave-convex nonlinearities and multiple Hardy-type terms is considered. By means of a variational method, we establish the existence and multiplicity of positive solutions for problem $\left(E_{\lambda }\right)$.
