具有时滞的Holling-Ⅲ型捕食系统的Hopf分支
Hopf Bifurcation in a Holling-Ⅲ Predator System with Time Delay
摘要
Abstract
In this paper,a Holling-Ⅲ predator-prey system with time delay under the homogeneous Neumann boundary conditions is studied.Firstly,by choosing the time delay as the bifurcation parameter,we study the effect of time delay on the stability of the posi-tive equilibrium point of the system,thereby the conditions for generating Hopf bifurcations are obtained.Secondly,with the aid of partial functional differential equations of center manifold theory and standard method,the direction of the Hopf bifurcations and sta-bility of periodic solutions of a bifurcation are gained.Finally,by using the numerical simulation function of MATLAB software,the theoretical results proposed in the paper are tested.关键词
