China QT1r V u p x u pxP dx p x Abstract In this article we study the nonlocal p x -Laplacian problem of the following form flCC px VufW u p x dx div Vu p x 2Vu u p x 2u b fn F x u dx f x u in .d u . . V ufW 2 g x u on 3 dv where Q is a smooth bounded domain and V is the outward normal vector on the boundary dQ and F x u f x t dt. By using the variational method and the theory of the variable exponent Sobolev space under appropriate assumptions on f g a and b we obtain some results on existence and multiplicity of solutions of the problem.

Since the 0 equation contains an integral related to the unknown u over o it is no longer an identity pointwise and therefore is often called nonlocal problem.
