Title: Generating Coxeter Groups by Reflections
Abstract:
Given a Coxeter system \((W,S)\), its set of reflections \(T\) yields another natural generating set for \(W\). I will talk about minimal generating sets of \(W\) contained in \(T\) (for \(W\) finite or affine) and about presentations of \(W\) for these minimal generating sets.
