摘要
在这篇文章中,我们在有界域Ω上分别考虑了包含p(x)-Laplacian算子的Neumann型的微分包含问题和Dirichlet型的微分包含问题在对非线性项作适当假设后,我们分别在变指数Sobolev空间W~(1,(p(x)))(Ω)和W_0~(1,(p(x)))(Ω)中,利用非光滑型Ricceri变分原理得到了两类问题的无穷多解性.
In this paper, we consider differential inclusion problem in a bounded domainΩ, involving p(x)-Laplacian of Neumann-typeand Dirichlet-typeWith some suitable assumptions on nonlinearities, the existences of infinitely many solutions are obtained by using nonsmooth version Ricceri's variational principle in variable exponent Sobolev spaces W~(1,(p(x)))(Ω) and W_0~(1,(p(x)))(Ω), respectively.
