Survival Analysis of a Delay Prey-predator System with Random Perturbations
摘要
Abstract
A delay prey-predator system with random perturbations is proposed and stud-ied. Under a simple assumption, almost sufficient conditions for stability in time average and extinction of each population are established. The critical value between stability in time average and extinction is obtained. Finally, numerical simulations are introduced to support the main results by Matlab.关键词
