| Abstract | The existence of positive periodic solutions for a delayed discrete predator-prey model withHolling-type-III functional responseN1(k+1)=N1(k)exp{b1(k)−a1(k)N1(k − [τ1]) −α1(k)N1(k)N2(k)/(N21 (k) +m2N22 (k))}, N2(k + 1) = N2(k)exp{−b2(k) + α2(k)N21 (k − [τ2])/(N21 (k − [τ2]) +m2N22 (k − [τ2]))} is established by using the coincidence degree theory. We also present sufficient conditions for the globally asymptotical stability of this system when all the delays are zero. Our investigation gives an affirmative exemplum for the claim that the ratio-dependent predator-prey theory is more reasonable than the tra-ditional prey-dependent predator-prey theory. 1. |
