The ring of stable characters over $GL_{∙} (q)$

Danielle Ernst-West, Doron Puder, Yotam Shomroni

For a fixed prime power $q$ , let $GL_{∙} (q)$ denote the family of groups $GL_{N} (q)$ for $N \in Z_{\geq 0}$ . In this paper we study the $C$ -algebr…

Some Orbits of Free Words that are Determined by Measures on Finite Groups

Liam Hanany, Chen Meiri, Doron Puder

Every word in a free group $F$ induces a probability measure on every finite group in a natural manner. It is an open problem whether two words that induce the same measure on ever…

Automorphism-invariant positive definite functions on free groups

Benoît Collins, Michael Magee, Doron Puder

In this article we raise some new questions about positive definite functions on free groups, and explain how these are related to more well-known questions. The article is intende…

Aldous' Spectral Gap Conjecture for Normal Sets

Ori Parzanchevski, Doron Puder

Let $S_{n}$ denote the symmetric group on $n$ elements, and $Σ \subseteq S_{n}$ a symmetric subset of permutations. Aldous' spectral gap conjecture, proved by Caputo, Liggett and Rich…

Matrix Group Integrals, Surfaces, and Mapping Class Groups I: $U (n)$

Michael Magee, Doron Puder

Since the 1970's, physicists and mathematicians who study random matrices in the GUE or GOE models are aware of intriguing connections between integrals of such random matrices and…
