Topology Seminar is back
by Hoffman, Neil 28 Sep '21

28 Sep '21

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.

Today in (Virtual) Topology Seminar
by Hoffman, Neil 07 Sep '21

Hello everyone, Today in topology I will be speaking. My title and abstract are below followed by the zoom link: 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. Neil Hoffman is inviting you to a scheduled Zoom meeting.
