Hello everyone,

Today Christian Millichap will be speaking in seminar. Robert is organizing a lunch today so meet at 12:30 outside his office if you are interested in that.

Christian's title and abstract are given below.

Title: Commensurability classes of fully augmented pretzel links

Speaker: Christian Millichap, Furman University

Date: Mar 26, 2019

Time: 3:30 PM

Room: MSCS 509

Abstract: Fully augmented links (FALs) are a large class of links whose complements admit hyperbolic structures that can be explicitly described in terms of combinatorial information coming from their respective link diagrams. In this talk, we will examine an infinite subclass of FALs that are constructed by fully augmenting pretzel links and describe how to build their hyperbolic structures. We will then discuss how we can use the geometries of these link complements to analyze arithmetic properties and commensurability classes of these links. This is joint work with Jeffrey S. Meyer and Rolland Trapp.
