Rank fluctuations of matrix products and a moment method for growing groups

Hoi H. Nguyen, Roger Van Peski

We consider the cokernel $G_{n} = Cok (A_{k} \dots A_{2} A_{1})$ of a product of independent $n \times n$ random integer matrices with iid entries from generic nondegenerate dis…

Symmetric functions and the explicit moment problem for abelian groups

Roger Van Peski

Recently, Sawin and Wood (arXiv:math/2210.06279) proved a formula for the distribution of a random abelian group $G$ in terms of its $H$ -moments $\mathbb{E} [\#\operatorname{Sur}(G…
