报告摘要： In this paper, we consider the problem of two-sample test of large networks with community structures. A test statistic is proposed based on the maximum entry of the difference between the two adjacency matrices. Asymptotic null distribution is derived and the asymptotic power against the alternative hypothesis is provided. Simulations and real data examples show that the proposed test statistic performs well.
