一类非局部竞争Lotka-Volterra系统的相互包含

The Mutual Inclusion in a Nonlocal Competitive Lotka Volterra System

Xiaojie hou, Biao Wang, Zhence Zhang

摘要:

研究了一类非局部Lotka-Volterra系统的行波解,以说明两种群竞争的结果.通过一种新的单调迭代格式得到了波前解的存在性,利用适用于非局部系统的滑动域方法证明了每种传播速度对应的波前解的唯一性,并采用一种不同于单方程情形的新方法得到了临界和非临界波速波前的渐近衰减率.结果表明,从长远来看,两个弱竞争物种可以共存。

英文摘要:

We investigate the traveling front solutions of a nonlocal Lotka Volterra system to illustrate the outcome of the competition between two species. The existence of the front solution is obtained through a new monotone iteration scheme, the uniqueness of the front solution corresponding to each propagation speed is proved by sliding domain method adapted to nonlocal systems, and the asymptotic decay rate of the fronts with critical and noncritical wave speeds is derived by a new method, which is different from the single equation case. The results demonstrate that in the long run, two weakly competing species can co-exist.
