非合作KPP系统:行波的渐近行为

Non-cooperative Fisher--KPP systems: asymptotic behavior of traveling waves

Léo Girardin

摘要:

本文研究一类非合作抛物型反应扩散方程组,它与标量Fisher-KPP方程具有结构上的相似性。在以前的论文中,我们建立了这些系统承认行波解。因此,研究它们的渐近分布是很自然的。这是本文的主要研究对象。非合作KPP系统可以模拟各种现象,其中发生以下三种机制:空间中的局部扩散,线性合作和超线性竞争。

英文摘要:

This paper is concerned with non-cooperative parabolic reaction--diffusion systems which share structural similarities with the scalar Fisher--KPP equation. In a previous paper, we established that these systems admit traveling wave solutions. It is then natural to investigate their asymptotic distributions. This is the main object of this paper. Non-cooperative KPP systems can model various phenomena where the following three mechanisms occur: local diffusion in space, linear cooperation and superlinear competition.
