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