Graph braid groups
Geometry/Topology| Speaker: | Lucas Sabalka, UC Davis |

Description
Artin's classical and much studied braid groups may be
defined in terms of configuration spaces on a disk. Replacing the
disk with a graph, we may study braid groups on graphs. I will define
graph braid groups in more detail and discuss various aspects of them,
hopefully including a solution to the isomorphism problem in some
cases. The talk will be aimed at graduate students.
