On the existence and stability of a unique almost periodic sequence solution in discrete predator-prey models with time delays. (English) Zbl 1228.39012

Summary: We consider an almost periodic discrete predator-prey model with time delays. Sufficient conditions for the permanence of the system and the existence of a unique uniformly asymptotically stable positive almost periodic sequence solution are obtained by the theory of difference inequality and the work of S.N. Zhang and G. Zheng [Appl. Math. Comput. 131, No. 2–3, 497–516 (2002; Zbl 1029.39011)]. Some suitable examples are employed to illustrate the feasibility of the main results.
