Existence of Periodic Solution for a Predator-prey System with Feedback Control
Hassell-Varely type predator-prey coincidence degree theorem Lyapunov function global stability
2012/9/24
A Hassell-Varely type predator-prey system with feedback controls is studied. Using the comparison, continuation theorems and coincidence degree theorem, the existence of positive periodic solutions f...
Periodic solutions for a predator-prey system with dispersal and semi-ratio-dependent functional response
functional response periodic solution dispersal coincidence
2010/9/10
By using a continuation theorem of Mawhin’s coincidence degree , studied a periodic predator-prey system with dispersal and semi-ratiofunctional response, sufficient conditions are obtained for the ex...
Existence of Limit Cycles in a Predator-Prey System With a Functional Response of the Form Arctan(ax)
Predator prey system limit cycle unctional response
2008/11/25
We consider a predator prey system with the functional response of the form
µ(x) = arctan(ax); a > 0. The main concern in this paper is the existence of
limit cycles for such system. A necessa...

Predator--prey system Limit cycle Uniqueness Dulac function
2007/12/11
The qualitative properties of a predator{prey system with Holling-(n + 1) functional response and a fairly general growth rate are completely investigated. The necessary and sufficient condition to gu...

Predator-prey system Limit cycle Bogdanov-Takens bifurcation
2007/12/11
In this paper the dynamical behaviors of apredator-prey system with Holling Type-IV functional response are investigated in detail by using the analyses of qualitative method, bifurcation theory,...
Optimal Harvesting and Stability for a Predator-prey System with Stage Structure
optimal harvesting stage structure predator-prey system
2007/12/10
The dynamics of a predator-prey system, where prey population has two stages, an immature stage and a mature stage with harvesting, the growth of predator population is of Lotka-Volterra nature, are m...
Periodic Solutions and Global Asymptotic Stability of a Delayed Discrete Predator-Prey System with Holling II Type Functional Response
Coincidence degree discrete predator-prey system global asymptotic stability positive periodic solutions
2007/8/7
In this paper, we study the existence and global asymptotic stability of positive periodic solutions of a delayed periodic predator-prey system with Holling II type functional response. By use of the ...
In this paper we consider the Predator-Prey model for three species in which the right-hand sides are periodic in time. A set of easily verifiable sufficient conditions is obtained for the existence o...
LOCAL AND GLOBAL BIFURCATIONS AND APPLICATIONS IN A PREDATOR-PREY SYSTEM WITH SEVERAL PARAMETERS
Bifurcation of equilibria Hopf bifurcat
2007/8/7
A predator-prey system, depending on several parameters, is investigated forbifurcation of equilibria, Hopf bifurcation, global bifurcation occurring saddle connection, and global existence and nonexi...
