The Space of Traces of the Free Group and Free Products of Matrix Algebras

Joav Orovitz, Raz Slutsky, Itamar Vigdorovich

We show that the space of traces of the free group $F_{d}$ on $2 \leq d \leq \infty$ generators is a Poulsen simplex, i.e., every trace is a pointwise limit of extreme traces. This f…

Spectral gap and character limits in arithmetic groups

Arie Levit, Raz Slutsky, Itamar Vigdorovich

We establish vanishing results for limits of characters in various discrete groups, most notably irreducible lattices in higher rank semisimple Lie groups. As an application, we sh…
