异质环境中具有一般边界条件的反应扩散病毒模型

On a reaction-diffusion virus model with general boundary conditions in heterogeneous environments

Mingxin Wang, Lei Zhang

AI总结:

本文构建含四类宿主与媒介种群的时间周期反应扩散病毒模型,证明正周期解的存在充要条件及其唯一性与全局渐近稳定性。

摘要:

为描述西尼罗河病毒和/或寨卡病毒的传播,本文提出并研究了一个时间周期反应扩散模型。该模型处于异质环境中,具有一般边界条件,并包含四个未知量:易感宿主、感染宿主、易感媒介和感染媒介。我们可以证明,当且仅当宿主与媒介持续存在且基本再生数大于1时,该问题存在正的时间周期解;此外,当正时间周期解存在时,它是唯一的且全局渐近稳定。

英文摘要:

To describe the propagation of West Nile virus and/or Zika virus, in this paper, we propose and study a time-periodic reaction-diffusion model with general boundary conditions in heterogeneous environments and with four unknowns: susceptible host, infectious host, susceptible vector and infectious vector. We can prove that such problem has a positive time periodic solution if and only if host and vector persist and the basic reproduction ratio is greater than one, and moreover the positive time periodic solution is unique and globally asymptotically stable when it exists.
