Reflection length on Coxeter groups Swiatos law R. Gal ´

Abstract: In the first hour I would discuss properties of biinvariant metrics on (discrete) groups. In the second I would present the prof of a theorem by Kamil Duszenko that the reflection length (which is also biinvariant word metric) on nonaffine Coxeter groups is unbounded.
