Influence of growth speed on the actors'' degree distribution of collaboration networks
增长速度对合作网络参与者节点度分布的影响

We present an analytical analysis of the actors' degree distribution of collaboration networks by the rate equation approach. The results show that the actors' degree follows a Yule-Simon distribution and this distribution can be well approximated by a shifted power law function. We find that the actors' degree distribution has a large deviation from power-law with the increase of the growth speed of actors. It indicates that the growth speed of actors is another key factor influencing the topological prope...
