Asymptotic normality for triangle counting in the sparse ${\hat{I}}^2$-model

Siang Zhang, Qunqiang Feng, Zhishui Hu

We study the number of triangles $T_n$ in the sparse ${\hat{I}}^2$-model on $n$ vertices, a random graph model that captures degree heterogeneity in real-world networks. Using the norms of…
