What is... a Coxeter group?
Benjamin Brück will explain what a Coxeter group is.
Abstract: Coxeter groups are a family of groups that are easily defined using generators and relations but have many interesting geometric and combinatorial properties. They occur in many areas of mathematics, e.g. as Weyl groups in Lie theory. I will give a short introduction to this family of groups, talk about basic properties and present examples.
