摘要
对一类具有生育脉冲和无穷分布时滞的n种群Lotka-Volterra系统,利用重合度理论中的连续性定理,得到了存在正周期解的一个充分条件.
This paper dealt with the n-species Lotka-Voherra system with infinite distributed delays and impulses. By applying the continuation theorem of coincidence degree theory, a set of easily sufficient conditions for the existence of positive periodic solutions was obtained.
