Probabilistic Hanna Neumann Conjectures

Yotam Shomroni

We develop a theory of polymatroids on Stallings core graphs, which provides a new technique for proving lower bounds on stable invariants of words and subgroups in free groups $F$ …

Stable Invariants of Words from Random Matrices II: Formulas and Extensions

Doron Puder, Yotam Shomroni

Let $w$ be a word in a free group. As was revealed by Magee and Puder in [arXiv:1802.04862], the stable commutator length (scl) of $w$ , a well-known topological invariant, can also…

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…
