扩散和强竞争系统的行波:相对运动性和侵入速度

Travelling waves for diffusive and strongly competitive systems: relative motility and invasion speed

Léo Girardin, Grégoire Nadin

摘要:

我们在这里的兴趣是找到两个物种,扩散和竞争的Lotka-Volterra系统的行波解的特定情况下的入侵者。我们研究扩散在均匀域中的作用。我们可以预期先验的两种不同的情况:强种间竞争和弱种间竞争。本文研究了第一种情况,得到了一个明确的结论:在一定的增殖常数下,入侵物种是扩散性更强的物种。

英文摘要:

Our interest here is to find the invader in a two species, diffusive and competitive Lotka-Volterra system in the particular case of travelling wave solutions. We investigate the role of diffusion in homogeneous domains. We might expect a priori two different cases: strong interspecific competition and weak interspecific competition. In this paper, we study the first one and obtain a clear conclusion: the invading species is, up to a fixed multiplicative constant, the more diffusive one.
