Permanence of a predator-prey discrete system with Holling-IV functional response and distributed delays.

A predator-prey discrete-time model with Holling-IV functional response and distributed delays is investigated in this paper. By using the comparison theorem of the difference equation and some analysis technique, some sufficient conditions are obtained for the permanence of the discrete predator-prey system. Two examples are given to illustrate the feasibility of the obtained result. [ABSTRACT FROM AUTHOR]
