Existence and Multiplicity of Solutions for p(x)-Kirchhoff-Type Problem in RN
Mei-Chun Wei and Chun-Lei Tang
Abstract.
In this paper we study the p(x)-Kirchhoff-type problem
{−m(∫RN1p(x)|∇u|p(x)dx)div(|∇u|p(x)−2∇u)+|u|p(x)−2u=f(x,u)Tin RNu∈W1,p(x)(RN).
We first establish the compact imbedding W1,p(x)(RN)↪Lq(x)b(x)(RN), where Lp(x)b(x)(RN)={u is measurable on RN:∫RNb(x)|u|p(x)dx<∞}. Based on it, the existence and multiplicity of solutions for the problem are obtained by variational methods.
