Periodic solutions of a periodic two-species competition model with delays. (English) Zbl 1043.34074
The authors establish the existence of a positive periodic solution of a two-species competition model with delays by means of the topological degree method, and obtain a set of natural and easily verifiable sufficient conditions for the existence of periodic solutions.
