Multiplicity of solutions for an anisotropic variable exponent problem

Abstract

Abstract In this manuscript an existence result for an anisotropic variable problem which is related to several applications is proved. By considering suitable hypotheses, the multiplicity of solutions is obtained. Examples of applicability of the results are also presented. The arguments are based on appropriated L ∞ $L^{\infty }$ estimates, sub-supersolutions, and the mountain pass theorem.
