Existence of Generalized Homoclinic Solutions of Lotka-Volterra System under a Small Perturbation
Keyword(s):
This paper investigates Lotka-Volterra system under a small perturbationvxx=-μ(1-a2u-v)v+ϵf(ϵ,v,vx,u,ux),uxx=-(1-u-a1v)u+ϵg(ϵ,v,vx,u,ux). By the Fourier series expansion technique method, the fixed point theorem, the perturbation theorem, and the reversibility, we prove that nearμ=0the system has a generalized homoclinic solution exponentially approaching a periodic solution.
