摘要: 建立一类带第一特征值λ1的具临界指数的半线性椭圆方程 -Δu=λ1u+|u|2*-2u零边值问题的非平凡弱解存在 的一个必要条件, 并在加权情况下得其相应结论.

关键词: 半线性椭圆方程, Sobolev临界指数, 第一特征值, 加权函

Abstract: In this paper, a necessary condition on the existence of a non-trivia l solution for the semi-linear elliptic equation (-Δu=λ1u+|u|2 *-2u) with zero boundary, the critical Sobolev exponents and the eigenvablue (λ1) is given, so is obtained the correspondent co nclusion in weighted condition.

Key words: semi-linear elliptic equation, critical Sobolev exponent, first eigenvalue, weight function
