讨论了一类具有非光滑位势的p(x)-Laplace非线性椭圆问题.利用非光滑的三临界点定理证明了该问题在变指数Sobolev空间W01,p(x)(Ω)中至少存在3个非平凡解.
A class of nonlinear elliptic proplem driven by p(x)-Laplacian with a nonsmooth locally Lipschitz potential was considered. Applying the version of non-smooth three-critical-point theorem, existence of three solutions of the problem in W01,P(x) (Ω) was proved.
