Hello everyone,
Topology seminar is back from our hiatus. Today we are very happy to have Jonathan Johnson speaking in seminar.
Hello everyone,
Today in topology I will be speaking. My title and abstract are below followed by the zoom link:
Title: Bi-Orderability Techniques and Double Twist Links
Speaker: Jonathan Johnson, Oklahoma State University
Date: Sep 28, 2021 Time: 3:00 PM
Room: Virtual
Abstract: The bi-orderability of link groups has become a fascinating research topic. In this talk, we will survey some useful tools that have been developed to investigate the bi-orderability of link complements, including results of Linnell-Rhemtulla-Rolfsen, Ito, and Kin-Rolfsen. In particular, we will apply these techniques to the double twist link groups.
Neil Hoffman is inviting you to a scheduled Zoom meeting.

Title: Bounds for arithmetic invariants of 3-manifolds
Speaker: Neil Hoffman, Oklahoma State University
Date: Sep 7, 2021
Time: 3:00 PM
Room: Virtual meeting Abstract:
A hyperbolic 3-manifold is the quotient of $H^3$ by $\Gamma$ a discrete subgroup of $PSL(2, C)$. In fact, this subgroup $\Gamma$ carries a substantial amount of arithmetic information. I will discuss some of the background for defining a hyperbolic 3-manifold this way and show how this leads to upper bounds on the degrees of fields used define this data. Finally, I will describe how this perspective fits into joint work with K. Petersen.
