具有优先连接和节点去除的网络模型中的拓扑相变

Topological phase transition in a network model with preferential attachment and node removal

Heiko Bauke, Cristopher Moore, Jean-Baptiste Rouquier, David Sherrington

摘要:

偏好依恋是一种流行的网络增长模型。我们考虑一个广义模型,随机节点删除,并结合优惠和随机连接。使用主方程的高度扩展,我们确定了一个拓扑相变取决于节点去除率和优先与随机连接的相对强度,其中度分布从幂律到指数尾。

英文摘要:

Preferential attachment is a popular model of growing networks. We consider a generalized model with random node removal, and a combination of preferential and random attachment. Using a high-degree expansion of the master equation, we identify a topological phase transition depending on the rate of node removal and the relative strength of preferential vs. random attachment, where the degree distribution goes from a power law to one with an exponential tail.
