Polynomial equations for matrices over integers modulo a prime power and the cokernel of a random matrix

Gilyoung Cheong, Yunqi Liang, Michael Strand

Given a prime $p$ and a positive integer $k$ , let $M_{n} (Z / p^{k} Z)$ be the ring of $n \times n$ matrices over $Z / p^{k} Z$ . We consider t…

Jordan--Landau theorem for matrices over finite fields

Gilyoung Cheong, Jungin Lee, Hayan Nam +1

Given a positive integer $r$ and a prime power $q$ , we estimate the probability that the characteristic polynomial $f_{A} (t)$ of a random matrix $A$ in $\mathrm{GL}_{n}(\mathbb{F}_…
