Sharp threshold for universality of cokernels of classical random matrix models over the $p$ -adic integers

Jiwan Jung, Jungin Lee, Myungjun Yu

We prove that $\frac{l o g n}{n}$ is the sharp threshold for universality of the distribution of cokernels of random matrices over $Z_{p}$ . More precisely, let $Î±_n = \frac{…

On the convergence of the graph sequence ${C^{m} (D)}_{m = 1}^{\infty}$ for a multipartite tournament $D$

Ji-Hwan Jung, Suh-Ryung Kim, Hyesun Yoon

Given a positive integer $m$ , the $m$ -step competition graph of a digraph $D$ , denoted by $C^{m} (D)$ , has the same vertex set as $D$ and has an edge between vertices $u$ and $v$ if a…
