Hello everyone,
You are receiving this email because you signed up for the topology list some time before now.
If you would like to be left off the list let me know and I can do that for you.
If not, then this week I will be speaking in seminar.
The zoom link for my talk is (full zoom info is at the end of the email):
Title: Fully Augmented Link complements and Bianchi Groups
Speaker: Neil Hoffman, Oklahoma State
Date: Feb 15, 2022
Time: 3:00 PM Room: Virtual
Abstract:
A Bianchi group is $PSL(2,O_d)$ for some $O_d$, the ring of integers in a quadratic imaginary field. These are some of the first and most well-studied Kleinian groups. A fully augmented link (FAL) is a natural diagrammatic object and its complement tends
to have nice geometric properties as well. Some of the simplest FAL complements also cover the quotients of $H^3$ by Bianchi groups. In some sense, both objects give standard examples in 3-manifold topology.
Two natural questions are then: 1) which fully augmented link complements have this property? 2) which Bianchi groups contain a fully augmented link group? As part of joint work (in progress) with Will Worden, we can answer both of these questions save a few
boundary cases. An interesting corollary of our work so far is that no FAL complement decomposes into regular ideal tetrahedra.
