网络分析的链空间形式

Link-space formalism for network analysis

David M. D. Smith, Chiu Fan Lee, Jukka-Pekka Onnela, Neil F. Johnson

摘要:

我们介绍了链接空间形式主义分析网络模型的度度相关。该形式主义是基于一个统计描述的部分链接l_{i,j}连接节点的度i和j。为了证明其使用,我们应用框架的一些教学网络模型,即随机附件,Barabasi-阿尔伯特优先附件和经典的鄂尔多斯和Renyi随机图。对于这三种模型,可以解析地求解链路空间矩阵。我们应用的形式主义一个简单的单参数增长网络模型,其数值解的度度相关性的影响,所得到的度分布。我们还采用的形式主义,以获得两个非常简单的网络衰减模型,更具体地说,随机链接删除和随机节点删除的度分布。该形式主义允许详细分析网络内的相关性,我们还利用它来推导出任意度分布的完全非线性网络的形式。

英文摘要:

We introduce the link-space formalism for analyzing network models with degree-degree correlations. The formalism is based on a statistical description of the fraction of links l_{i,j} connecting nodes of degrees i and j. To demonstrate its use, we apply the framework to some pedagogical network models, namely, random-attachment, Barabasi-Albert preferential attachment and the classical Erdos and Renyi random graph. For these three models the link-space matrix can be solved analytically. We apply the formalism to a simple one-parameter growing network model whose numerical solution exemplifies the effect of degree-degree correlations for the resulting degree distribution. We also employ the formalism to derive the degree distributions of two very simple network decay models, more specifically, that of random link deletion and random node deletion. The formalism allows detailed analysis of the correlations within networks and we also employ it to derive the form of a perfectly non-assortative network for arbitrary degree distribution.
