摘要:

该文讨论一个几乎临界增长的半线性椭圆方程.证明了对相应的格林函数的每个严格的局部极小点x0,所考虑的问题有一个正解集中在x0.

关键词: 临界指数, 半线性, 椭圆方程, 正解.

Abstract:

 This paper deals with a semiliear elliptic equation involving nearly critical Sobolev exponent. We prove that for each strictly local maximun point x0 of he related Green's function, the problem has a positive solution,concentrating at x0.

Key words: critical exponent, semilinear, elliptic equation, positive solution.
