DESCRIPTION:Title: Centers of Artin groups.\n\nAbstract: Artin groups are a
  family of groups generalizing braid groups and closely related to Coxeter
  groups. They can be realized as the fundamental groups of certain complex
  hyperplane arrangements\, which conjecturally are their K(pi\,1) spaces. 
 This is known as the K(pi\,1) conjecture. There is also a conjectural desc
 ription of the center of every Artin group. Irreducible Artin groups\, i.e
 . those that do not split as direct products\, are conjectured to have tri
 vial centers\, unless they are of finite type\, in which case they are kno
 wn to have infinite cyclic centers. In my talk\, I will present joint work
  with Kevin Schreve\, where we show that the Artin groups satisfying the K
 (pi\,1) conjecture also satisfy the center conjecture.\n
