摘要 研究了一类含有奇异项和超线性项的半线性椭圆边值问题 .利用变分法和上下解方法 ,证明了正解的存在性和唯一性 。 Using variational method as well as super-lower solution method, the authors consider the existence and uniqueness of positive solution of the singular semi-linear elliptic boundary value problems. The results can be viewed as an extension and improvement of many related known results.
