摘要

本文利用DDE对成熟猎物捕食的捕食者-捕食者模型进行建模和分析。计算平衡点，并对非零平衡点进行稳定性分析。当时滞参数值低于临界点时，时滞参数会使系统失稳，并触发系统渐近稳定。当延迟参数值越过临界点时，出现Hopf分岔。对其他参数对状态变量的影响也进行了敏感性分析。利用MATLAB对数值结果进行了验证。

Modelling and analysis of prey-predator model involving predation of mature prey using delay differential equations

In this paper, the modelling and analysis of prey-predator model involving predation of mature prey is done using DDE. Equilibrium points are calculated and stability analysis is performed about non-zero equilibrium point. Delay parameter destabilizes the system and triggers asymptotic stability when value of delay parameter is below the critical point. Hopf bifurcation is observed when the value of delay parameter crosses the critical point. Sensitivity analysis has also been performed to look into the effect of other parameters on the state variables. The numerical results are substantiated using MATLAB.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
