Summary

Introduction

The study of differential equations and variational problems with nonstandard p(x)growth conditions is a new and interesting topic. In [4, 7], Fan and Zhao give the regularity of weak solutions for differential equations with nonstandard p(x)-growth conditions. On the existence of solutions for p(x)-Laplacian problems in bounded domain, we refer to [5, 11, 12]. We consider the p(x)-Laplacian equations with singular nonlinearities:. There are many results on the existence of positive solutions for p-Laplacian problems with singular nonlinearities (see [14,15,16,17,18]), but the results on the existence of positive solutions for p(x)-Laplacian problems with singular nonlinearities. Our results partially generalized the results of [18]
