Artin groups of infinite type: trivial centers and acylindical hyperbolicity (1805.04028v2)
Published 10 May 2018 in math.GR
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 $A_\Gamma$ on a CAT(0) cube complex to prove that $A_\Gamma$ has trivial center providing the graph $\Gamma$ is not the star of a single vertex, and is acylindrically hyperbolic providing $\Gamma$ is not a join.
