霍乱流行的空间模拟:一个Law of Large Numbers

Spatial modeling of cholera epidemic: A Law of Large Numbers

Boris Kouegou Kamen, Mac Jugal Nguepedja Nankep

摘要:

在本文中,我们提出了一个随机模型来研究空间霍乱流行病蔓延的社区(人类和细菌)在空间上分布在一个一维的晶格和细菌被运送沿网络链接,被认为是在研究区域的水文连接。我们证明了一个大数定律,这表明在大社区(人类和细菌)的随机模型表现为一个确定性的空间模型提出和研究的文献,因此,它是不可避免的要问如何大的波动效应可以发生在这两个版本之间。这个问题将被视为大偏差估计在即将到来的工作。我们还讨论了在工作结束时,可以使用类似的数学工具,并导致不同的限制不同的可能的缩放。

英文摘要:

In this paper we propose a Stochastic model for studying a spatial cholera epidemic spreading where communities (Humans and Bacteria) are spatially distributed on a one-dimensional lattice and the bacteria are transported along a network links that are thought as the hydrological connection in the studied area. We prove a Law of Large numbers which suggest that in large communities (both Human and Bacteria) the stochastic model behave as a deterministic spatial model proposed and studied in the literature and therefore it is quite unavoidable to ask how large fluctuations effect can occur between these two version. That question will be treated in a forthcoming work as large deviations estimates. We also discuss at the end of the work different possible scaling that could be treated using similar mathematical tools and which lead to different limits.
