一类饱和竞争模型的正解

Positive Solutions of Competition Model with Saturation

Aung Zaw Myint, Li Li, Mingxin Wang

摘要:

本文主要讨论一类具有饱和项的扩散竞争模型的正解。在一定条件下,分析了共存态的稳定性和多样性。利用锥上的拓扑度理论,证明了在一定条件下该问题至少有两个正解。最后,研究了由半平凡解产生的共存态的分歧,给出了共存态的一些不稳定性和多重性结果。

英文摘要:

In this paper, the positive solutions of a diffusive competition model with saturation are mainly discussed. Under certain conditions, the stability and multiplicities of coexistence states are analyzed. And by using the topological degree theory in cones, it is proved that the problem has at least two positive solutions under certain conditions. Finally, investigating the bifurcation of coexistence states emanating from the semi-trivial solutions, some instability and multiplicity results of coexistence state are expressed.
