Existence and multiplicity of solutions for a singular anisotropic problem with a sign-changing term

Existence and multiplicity of solutions for a singular anisotropic problem with a sign-changing term

In this paper we investigate the existence and multiplicity of solutions for a class of singular anisotropic problems involving a weight and a term that may change sign. The approach is based on sub-supersolutions and the Mountain Pass Theorem.
