摘要
主要研究随机竞争Lotka-Volterra系统的周期系数,得到该方程周期解存在性和全局吸引性的充分条件.即使是在特殊情况下,结果也改进了文献(Jiang D,Shi N,Li X.J Math Anal Appl,2008,340(1):588-597.)中的结果.
The main aim of this paper is to study stochastic competition Lotka-Volterra model with periodic coefficients.We obtain the sufficient conditions for the existence and global attractivity of periodic solution to the equation. Even in the special cases,the results in research literrature( Jiang D,Shi N,Li X. J Math Anal Appl,2008,340( 1) : 588-597.) are improved.
