一般度分布稀疏随机图的谱统计

Spectral Statistics of Sparse Random Graphs with a General Degree Distribution

Ben Adlam, Ziliang Che

摘要:

我们考虑Chung-Lu模型中稀疏随机图的邻接矩阵,其中边以不同的概率$p_{ij}$独立地添加到$N$顶点之间.矩阵$(p_{ij})$的秩是某个固定的正整数。我们证明了特征值的分布由一个泛函自洽方程的解给出。我们证明了一个本地法律的最佳规模,并证明批量的普遍性。结果与\cite{Erdos2013b}和\cite{Landon2015}的结果一致。

英文摘要:

We consider the adjacency matrices of sparse random graphs from the Chung-Lu model, where edges are added independently between the $N$ vertices with varying probabilities $p_{ij}$. The rank of the matrix $(p_{ij})$ is some fixed positive integer. We prove that the distribution of eigenvalues is given by the solution of a functional self-consistent equation. We prove a local law down to the optimal scale and prove bulk universality. The results are parallel to \cite{Erdos2013b} and \cite{Landon2015}.
