一类Lasota-Wazewska模型渐近概周期解的研究

Lasota-Wazewska模型常被用来描述动物体内红血球的再生情况。本文针对一类Lasota-Wazewska模型,首先利用Banach压缩映射原理说明了在一定的条件下模型的严格正的渐近概周期解的存在唯一性,然后,构造合适的Lyapunov函数,说明这个渐近概周期解是全局指数渐近稳定的。本文结果能够使关于Lasota-Wazewska模型动力学行为的刻画更加丰富。

A New Approach for Impulsive Stabilization of Liu's System

An impulsive control scheme of Liu＇s system is presented in this paper. Some less conservative conditions with impulses at fixed times are provided, which can guarantee the global asymptotical stability and global exponential stability for the impulsive control of Liu＇s systems. We also present the estimate of the stable region for the equidistance impulsive interval. Furthermore, an illustrative example is given to show the effectiveness of the proposed results.
