摘要：
This paper presents several sufficient conditions for the existence of solutions for the Dirichlet problem of p(x)-Laplacian {-div(\delu\ (p(x)-2)delu) = f(x,u), x is an element of Omega, {u = 0, xis an element of partial derivativeOmega. Especially, an existence criterion for infinite many pairs of solutions for the problem is obtained. The discussion is based on the theory of the spaces L-p(x) (Omega) and W-0(1, p(x)) (Omega).
