On the discrete-time multi-species competition-predation system with several delays. (English) Zbl 1129.92067
Summary: We study a discrete-time multi-species ecological competition-predation system with several delays. By a new method of difference inequalities, it is shown that the system is permanent under some appropriate conditions. Moreover, we give an example to illustrate the feasibility of our result.
