摘要: 利用Liapunov-Schmidt方法证明了一类交叉扩散系统的发自平凡解的非平凡正定态解的存在性,并利用谱分析方法得到关于这个分歧解的稳定性的一个条件.

关键词: 交叉扩散系统, 分歧, 定态解

Abstract: In this paper a system with cross-diffusion effects is investigated. The existence of the nontrivial positive stationary solutions coming from the trivial solution is proved by the Lia-punov-Schmidt procedure. Moreover,a condition for the stability of the bifurcation solutions is obtained by spectral analysis.
