Permanence of a discrete periodic Volterra model with mutual interference and Beddington-DeAngelis functional response (Q980794)

Summary: This paper discuss a discrete periodic Volterra model with mutual interference and Beddington-DeAngelis functional response [cf. Appl. Math. Comput. 214, No. 2, 548--556 (2009; Zbl 1175.34058)]. By using the comparison theorem of difference equation, sufficient conditions are obtained for the permanence of the system. After that, we give an example to show the feasibility of our main result.
