holling ii 功能反应下具有时滞的捕食-食饵模型分析
首发时间:2024-01-16
摘要:主要研究了一个在holling ii 型功能反应函数下具有时滞的捕食-食饵模型的动力学行为. 首先讨论了正常数平衡解的稳定性,然后以时滞为分支参数对系统进行了分支分析. 研究表明,当参数满足一定条件时时滞对平衡点的稳定性不产生影响;否则当时滞较大时会产生hopf分支,系统存在周期解. 最后,通过数值模拟,验证了相关的理论结果.

analysis of predator-prey model with time delay under holling ii functional response
abstract:to study the dynamical behavior of a predator-prey model with time delay under the holling type ii functional response function. firstly, discuss the stability of the positive constant equilibrium. then the delay parameter is taken as the bifurcation parameter to analyze the system. the results show that when the parameters meet certain conditions, the delay does not affect the stability of the equilibrium point, otherwise the hopf bifurcation may occur when the delay is large , and the system generates periodic solutions. finally, through numerical simulation, verify the relevant theoretical results.
