摘要:

该文研究了一类具有不连续捕获项的非光滑混合时滞Lasota-Wazewska模型.基于非光滑分析、Kakutani's不动点理论和常Lyapunov方法,建立了易于验证的与时滞无关的稳定性准则,同时保证模型的正周期解的存在性和全局指数稳定性,并给出了对应的仿真实例来验证该文中方法的正确性和有效性.

关键词: Lasota-Wazewska模型, 混合时滞, 不连续捕获, 正周期解, 指数稳定

Abstract:

In this paper, we study a class of mixed time-varying delayed Lasota-Wazewska model with discontinuous harvesting, which is described by a periodic nonsmooth dynamical system. Base on nonsmooth analysis, Kakutani's fixed point method and the generalized Lyapunov method, easily verifiable delay-independent criteria are established to ensure the existence and exponential stability of positive periodic solutions. Finally, we give an example to further illustrate the effectiveness of our main results.

Key words: Lasota-Wazewska model, Mixed delayed system, Discontinuous harvesting, Positive periodic solution, Exponential stability
