摘要:

该文考虑一类带临界增长项的退化的椭圆型偏微分方程解的存在性, 利用变量代换的方法, 把方程转化为半线性方程, 再利用集中紧引理以及基于锥分解的环绕定理, 证明了方程解的存在性.

关键词: 椭圆型方程, 环绕定理, 临界指数

Abstract:

In this paper, we study a class of degenerative quasilinear elliptic equations with critical exponent. Using a change of variable, we reformulate the equation into a semilinear one, and prove the existence of solutions by employing Lions concentration compactness principle and linking theorem based on cone.

Key words: Elliptic equations, Linking thoerem, Critical exponent
