Title: "A geometric approach to Artin groups."
Speaker: Ruth Charney
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
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?
