Harmless delays in a discrete ratio-dependent periodic predator-prey system
Verifiable criteria are established for the existence of positive periodic solutions and permanence of a delayed discrete periodic predator-prey model with Holling-type II functional response N1(k+1)=N1(k)exp{b1(k)−a1(k)N1(k−[τ1])−α1(k)N2(k)/(N1(k)+m(k)N2(k))} and N2(k+1)=N2(k)exp{−b2(k)+α2(k)N1(k...
