### The isomorphism problem for tree braid groups

**Geometry/Topology**

Speaker: | Lucas Sabalka, UC Davis |

Location: | 2112 MSB |

Start time: | Wed, Jan 17 2007, 4:10PM |

This talk discusses tree braid groups. A tree braid group is the fundamental group of the space of all configurations of n distinct points on a given tree. I will give proofs of some statements used in the solutions of the isomorphism problem. This will, hopefully, make the talk interesting for those of you who heard my talk in the Fall.
