多种群中立型时滞脉冲系统周期解的存在性

Existence of positive periodic polutions of a neutral delay system of multiple-species with impulses

运用K-集压缩算子拓扑度抽象连续定理和某些分析技巧,在一定的条件下,得到多种群中立型时滞脉冲系统周期解的存在性.

By means of the abstract continuation theory for K - set contraction and some analytical skills, we obtain sufficient conditions for the existence of positive periodic solutions of a neutral delay system of multiple - species with impulses.
