摘要
研究环域上一类非线性二阶椭圆系统的正对径解的存在性和多解性.文章的主要思想是锥拉伸与锥压缩型的Krasnosel′skii不动点定理的局部应用.
In this paper we investigate the existence and multiplicity of positive radial solutions for a class of nonlinear second-order elliptic systems on annular domains. Our main ideal is local application of Krasnosel′skii fixed point theorem of cone expansion-compression type.
