Abstract: This article concerns the multiplicity of solutions for a class of nonlocal and nonhomogeneous Neumann boundary value problems involving the p(x)-Laplacian, in which both nonlinear terms assume critical growth. We use variational method, exploring an important truncation argument and properties of the genus.

Keywords: Nonlocal problem, Neumann boundary conditions, Sobolev spaces with variable exponent, critical exponent, truncation argument
