Talk by Prof. Dr. Nicolas Monod

I will review the Dixmier Problem, open since 1950, which asks for a condition ensuring that all representations of a given group are unitarisable. This can be related to analytic conditions and to geometric constructions such as random forests. I will also present recent work with Gerasimova, Gruber and Thom, where the Dixmier Problem is related to the asymptotic properties of isoperimetric constants.
