摘要:

本文主要关注双稳型Lotka-Volterra竞争系统中波速的符号,也称为强-强竞争情形。该系统的行波解对于理解Cauchy问题解的长时间行为至关重要。具体而言,波速的符号是预测竞争中哪个物种将胜出的关键。本文通过研究一个退化的Lotka-Volterra竞争系统,提出了两个用于判定波速符号的充分条件。

英文摘要:

This paper mainly focuses on the sign of the wave speed in the Lotka-Volterra competition system of bistable type, also known as the strong-strong competition case. The traveling wave solution of the system is crucial for understanding the long-time behavior of solutions to the Cauchy problem. Specifically, the sign of the wave speed is key to predicting which species will prevail in the competition. In this paper, by studying a degenerate Lotka-Volterra competition system, we propose two sufficient conditions for determining the sign of the wave speed.
