Title: "A geometric approach to Artin groups."
Speaker: Ruth Charney
Abstract: Artin groups arise naturally as fundamental groups of hyperplane complements. They form a large and diverse collection of groups which include braid groups, free groups, free abelian groups and many more. While some classes of Artin groups are well understood, many remain mysterious, with even very basic questions unanswered. In this talk, I will discuss some old and some new geometric techniques for understanding infinite type Artin groups. (Joint work with Rose Morris-Wright.)

The introductory talk will be a general introduction to Artin groups. What are Artin groups and why do we care? What is known and what is not known about these groups?
