摘要
讨论障碍函数ψ和参量λ对带有临界增长条件的拟线性椭圆障碍问题的正解的存在或不存在性的作用,得到了几个保证障碍问题的正解存在的必要条件.
The object of this paper is to discuss the function of the obstacle function ψ and parameter λ for existence or nonexistence of positive solutions to the quasilinear elliptic obstacle problem under critical Sobolev growth condition. Several necessary conditions to ensure the existence of positive solutions to obstacle problem are obtained.
