Global Asymptotic Stability of a Predator-Prey Model with Modified Leslie-Gower and Holling-Type II Schemes

الملخص EN

We study the predator-prey model proposed by Aziz-Alaoui and Okiye (Appl.

Math.

Lett.

16 (2003) 1069–1075) First, the structure of equilibria and their linearized stability is investigated.

Then, we provide two sufficient conditions on the global asymptotic stability of a positive equilibrium by employing the Fluctuation Lemma and Lyapunov direct method, respectively.

The obtained results not only improve but also supplement existing ones.
