                                        应用Guo-Krasnosel’skii不动点理论,在非线性项为变号函数的情形下,讨论离散Dirichlet问题,建立正解的存在性及多解性结果。
By using the Guo-Krasnosel’skii fixed point theorem, a Dirichlet boundary value problem with sign-changing nonlinearity is discussed and some results of existence and multiplicity of positive solutions are established.
