摘要

这项研究有助于理解涉及同类相食的延迟捕食系统。假设该系统使用Holling II型功能响应来描述消耗过程,并包含捕食者对同类相食过程的庇护。讨论了该溶液的特点。所有可能的平衡点都已确定。研究了各时滞值下各平衡点的局部稳定性分析。系统在共存平衡处表现出Hopf分岔,进一步证明了这一点。然后利用泛函微分方程的中心流形和范式定理,确定了Hopf分岔的方向和周期解的稳定性。为了证明关键的发现,然后运行各种数值模拟。

The dynamics of a delayed ecological model with predator refuge and cannibalism
: This study has contributed to understanding a delayed prey-predator system involving cannibalism. The system is assumed to use the Holling type II functional response to describe the consuming process and incorporates the predator's refuge against the cannibalism process. The characteristics of the solution are discussed. All potential equilibrium points have been identified. All equilibrium points' local stability analyses for all time delay values are investigated. The system exhibits a Hopf bifurcation at the coexistence equilibrium, which is further demonstrated. The center manifold and normal form theorems for functional differential equations are then used to establish the direction of Hopf bifurcation and the stability of the periodic solution. To demonstrate the key findings, various numerical simulations are then run.
