摘要
研究一类带Markovian跳的随机非自治Logistic种群模型,在种群内部竞争制约系数受到白噪声扰动情况下,运用指数鞅不等式技巧,揭示了该种群系统在Markovian切换状态下弱持久生存的充分性条件.最后,通过数值模拟验证了主要结果.
This paper considers a type of disturbance related with intraspecific interaction on non- autonomous Logistic competitive system in random environments. By using Doob＇s martingale inequalities method, some sufficient conditions for weak persistence on system with Markovian switching are established. Finally, numerical simulation is carried out to support the results.
