Solutions for Neumann boundary value problems involving $(p_1(x),p_2(x))$-Laplace operators

Duchao Liu, Xiaoyan Wang, Jinghua Yao

In this paper we study the nonlinear Neumann boundary value problem of the following equations -\text{div}(|\nabla u|^{p_{1}(x)-2}\nabla u)-\text{div}(|\nabla u|^{p_{2}(x)-2}\nabla…
