摘要
A Lotka–Volterra periodic delay model with m-predators and n-preys is studied in this paper. Sufficient conditions for the global existence of a positive periodic solutions of this delay model are obtained by means of topological degree. Finally, a suitable example is given to illustrate that the conditions of the main theorem are feasible.
