网络投票模型的异质对近似

Heterogeneous pair approximation for voter models on networks

Emanuele Pugliese, Claudio Castellano

摘要:

对于在网络上演化的模型,通常有必要通过明确考虑平均量的度依赖性(非均匀平均场)来增强平均场方法。在这里,我们介绍了度依赖的对近似(异构对近似)分析不相关网络上的投票模型。这种方法给出了一个基本上准确的动态描述,纠正了以前的方法的一些不准确的结果。这里介绍的异质对近似可以完全通用于复杂网络上的许多其他过程。

英文摘要:

For models whose evolution takes place on a network it is often necessary to augment the mean-field approach by considering explicitly the degree dependence of average quantities (heterogeneous mean-field). Here we introduce the degree dependence in the pair approximation (heterogeneous pair approximation) for analyzing voter models on uncorrelated networks. This approach gives an essentially exact description of the dynamics, correcting some inaccurate results of previous approaches. The heterogeneous pair approximation introduced here can be applied in full generality to many other processes on complex networks.
