Abstract

In this paper, using the Nehari manifold approach and some variational techniques, we discuss the multiplicity of positive solutions for the $p(x)$-Laplacian problems with non-negative weight functions and prove that an elliptic equation has at least two positive solutions.

Keywords: variable exponent Lebesgue-Sobolev spaces, $p(x)$-Laplacian, variational methods, Nehari manifold, multiple positive solutions
