摘要
本文研究一类带时滞的非自治随机竞争模型,利用It公式及比较定理,得到了两种群几乎时间均值稳定和局部灭绝的充分必要条件,并通过MATLAB仿真说明了主要结果.
An autonomous stochastic competitive system with delay is investigated. Almost sufficient and necessary conditions for stability in time average and extinction of each population are established by It's formula and the comparison theorem. And numerical simulations are introduced to support the main results via Matlab.
