异构网络上SIS流行病的超紧两两模型

Super compact pairwise model for SIS epidemic on heterogeneous networks

Péter L. Simon, Istvan Z. Kiss

摘要:

在本文中,我们提供了一个超紧凑的成对模型的推导过程中,只有4个方程的背景下,描述易感-感染-易感(SIS)的流行病动力学的异质网络。超紧模型是基于一个新的封闭关系,不仅涉及到平均度,但也二阶和三阶矩的度分布。它的推导使用了一个先验近似的敏感节点的度分布方面的网络的度分布。新的封闭提供了良好的协议与异质成对模型,包含显着更多的微分方程。

英文摘要:

In this paper we provide the derivation of a super compact pairwise model with only 4 equations in the context of describing susceptible-infected-susceptible (SIS) epidemic dynamics on heterogenous networks. The super compact model is based on a new closure relation that involves not only the average degree but also the second and third moments of the degree distribution. Its derivation uses an a priori approximation of the degree distribution of susceptible nodes in terms of the degree distribution of the network. The new closure gives excellent agreement with heterogeneous pairwise models that contain significantly more differential equations.
