Periodic Positive Solution of Nonautonomous Multiple Group Lotka-Volterra Competition System with Harvesting Rate
摘要
Abstract
A class Lotka-Voherra competition system with harvesting rate of n nonautonomous population was studied. By using the continuation theorem of the coincidence degree theory, a sufficient condition of positive periodic solutions existence of guarantee system was obtained. We reveal a Lotka-Voherra competition system of n nonautonomous population, and it will produce the biological periodic oscillation when the intrinsic growth rate is sufficiently large and competitive rates and yields are sufficiently small.关键词
