摘要:

利用Sobolev嵌入定理、 Lusin定理和Egoroff定理证明奇异椭圆问题有限能量解的不存在性, 并给出所研究问题存在有限能量解的充要条件.

关键词: 拟线性椭圆方程, Egoroff定理, 有限能量解

Abstract:

Using Sobolev embedding theorem, Lusin theorem and Egoroff theorem, we proved nonexistence of solutions to singular elliptic problems. At the same time, we also obtained a sufficient and necessary condition of existence of finite energy solutions.

Key words: quasilinear elliptic equation, Egoroff theorem, finite energy solution
