摘要
一类具有白噪声干扰的单种群间歇扩散模型被建立.通过构造合适的Lyapunov函数,全局正解的存在唯一性,随机最终有界性被得到.
A single-species intermittent dispersal model with stochastic perturbations between two patches is proposed and studied in the paper. By constructing appreciate Lyapunov functions, some conditions on the global existence and uniqueness of a positive solution, stochastically ultimate boundedness are established.
