Talk: On the isomorphism problem for Coxeter groups
Bernhard Muehlherr (University of Brussels, Belgium)
4:00pm, KER 317
Coxeter groups are groups generated by a set of involutions and which have a particularly nice presentation in terms of these generators. The finite Coxeter groups are precisely the finite real reflection groups; in particular, the automorphism groups of finite regular polytopes are Coxeter groups. The whole information of the "nice presentation" mentioned above is encoded in the so-called Coxeter matrix. Thus each Coxeter matrix M provides a Coxeter group W(M). In my talk I will consider the following question. Is there an algorithm to decide for two Coxeter matrices M and M' whether the associated Coxeter groups W(M) and W(M') are isomorphic?
