椭圆边值系统的正径向解的存在性与多解性<英>

Existence and Multiplicity of Positive Radial Solutions for Elliptic Boundary Value Systems

通过利用锥拉伸及锥压缩型的Krasnosel’skii不动点定理,我们研究了一类椭圆边值系统的正径向解的存在性,非存在性与多解性.

In this paper by use of the Krasnosel'skii fixed point theorem of cone expansion-compression type we investigate the existence, nonexistence and multiplicity of positive radial solutions for a class of elliptic boundary value systems.
