23rd Annual
Workshop in Geometric Topology
June 2-3-4, 2006
Oregon State University

PRINCIPAL SPEAKER
The principal speaker is Professor Ruth Charney of Brandeis University.  She will give three lectures.

Title: Right-Angled Artin Groups

 Abstract: Artin groups, defined by presentations of a simple form, span a wide range of groups from braid groups, to free groups, to free abelian groups. They are closely related to Coxeter groups and mapping class groups and are associated with a variety of geometric objects. After a brief, general introduction to Artin groups, the lectures will focus on a class of Artin groups known as "right-angled" Artin groups. These groups have proved particularly versatile and interesting, in part because of their actions on CAT(0) spaces.
