摘要
本文用特征理论及上下解方法,证明了一类半线性椭圆方程边值问题的正解的存在性,同时给出了解的估计.
In this paper,the eigenfunction theory and the upper-lower solution methods are used to prove the existence of the positive solutions to boun- dary value problem of semilinear elliptic equations,and the method of es- timating the solutions is given
