Permanence and Asymptotically Periodic Solution for A Cyclic Predator-Prey Model With Sigmoidal Type Functional Response
نویسندگان
چکیده
This paper is concerned with a cyclic predator-prey system with Sigmoidal type functional response. By using the differential inequality theory, some sufficient conditions are derived for the permanence of the system. By constructing a suitable Liapunov function, we obtain that the system has a unique asymptotically periodic solution which is globally asymptotically stable. Some numerical simulations that illustrate our analytical predictions are carried out. The paper ends with a brief conclusion. Key–Words: Predator-prey system, Permanence, Sigmoidal type functional response, Asymptotically periodic solution, Liapunov function; Global stability

Permanence and global asymptotic stability of a delayed predator-prey model with Hassell-Varley type functional response
Here, a predator-prey model with Hassell-Varley type functional responses is studied. Some sufficient conditions are obtained for the permanence and global asymptotic stability of the system by using comparison theorem and constructing a suitable Lyapunov functional. Moreover, an example is illustrated to verify the results by simulation.
متن کاملThreshold harvesting policy and delayed ratio-dependent functional response predator-prey model
This paper deals with a delayed ratio-dependent functional response predator-prey model with a threshold harvesting policy. We study the equilibria of the system before and after the threshold. We show that the threshold harvesting can improve the undesirable behavior such as nonexistence of interior equilibria. The global analysis of the model as well as boundedness and permanence properties a...
متن کاملQualitative Analysis in A Predator-prey Model with Sigmoidal Type Functional Response
In this paper, a cyclic predator-prey system with Sigmoidal type functional response is considered. The stability of the positive equilibrium and existence of Hopf bifurcation is studied by analyzing the distribution of the roots of associated characteristic equation. It is shown that the positive equilibrium is locally asymptotically stable when the time delay is small enough, while change of ...
متن کاملPermanence and Periodic Solution for a Predator- Prey Model with Mixed-Type Functional Response
In this paper, a predator-prey model with mixed-type functional response is investigated. Sufficient conditions are derived that guarantee the permanence of the system. Meanwhile, when the system is periodic, we obtain the sufficient conditions which guarantee the existence, uniqueness and global asymptotic stability of the positive periodic solution. Numerical simulations are also presented to...
متن کاملStudy on a non-autonomous predator-prey system with Beddington-DeAngelis functional response
In this paper, a predator–prey system with Beddington–DeAngelis functional response is studied, where the predator preys on n competing preys. We prove that the system admits very rich dynamics, including permanence, ultimate boundedness, extinction. Moreover, under some appropriate assumptions, there exists a unique almost periodic solution which is shown to be globally asymptotically stable.
