Analysis of Degree Distribution for a Duplication Model of Social Networks

Social networks have attracted remarkable attention from both academic and industrial societies, and it is of great importance to understand the structure of social networks. In this paper, we take a duplication model of social networks into consideration, and analyze the degree distribution of the generated network theoretically. All analysis results are verified by simulations. These results are of importance to understand the formation of social networks, and the model can be easily extended to consider more realistic situations.
