Artin groups of infinite type: trivial centers and acylindical hyperbolicity

Group Theory 2018-06-04 v2

Abstract

While finite type Artin groups and right-angled Artin groups are well-understood, little is known about more general Artin groups. In this paper we use the action of an infinite type Artin group AΓA_\Gamma on a CAT(0) cube complex to prove that AΓA_\Gamma has trivial center providing the graph Γ\Gamma is not the star of a single vertex, and is acylindrically hyperbolic providing Γ\Gamma is not a join.
