Today in Seminar

26 Mar '19

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. ______________________ Neil R.

Redbud registration

Hello everyone, If you haven't registered for Redbud, do it today, because the first registration deadline is TODAY: The registration link is here: http://www.math.ou.edu/conferences/redbud/spring-2019/ The last time I check I was the lone OSU person registered. If that holds, I suppose I will be driving to Norman with Eric Carmen on repeat. Obviously, I would just assume not do that. Best, Neil ______________________ Neil R.

Title: Which hyperbolic knot complements have hidden symmetries? Speaker: Jason Deblois, University of Pittsburgh Date: Mar 12, 2019 Time: 3:30 PM Room: MSCS 509 Abstract: Neumann and Reid asked the titular question in the early 1990’s, and it remains unresolved. I’ll survey what we have learned to this point, then discuss joint work with Eric Chesebro and Priyadip Mondal on exhibiting many families that lack hidden symmetries. ______________________ Neil R.

Hello everyone, The spring Redbud 2019 conference has been announced. It will be held at Norman this year April 26-28. If you are planning on going, please register by March 15 so it will help organizers* get a sense on numbers. It looks to be a good conference and I would encourage everyone to consider attending. Best, Neil * The real organizers are Max, Jing and Justin. I don't want to take any credit that is rightfully theirs. ---------- Forwarded message --------- From: Max Forester <mf(a)ou.edu<mailto:mf@ou.edu>> Date: Tue, Jan 22, 2019 at 12:20 PM Subject: 2019 Redbud Topology Conference: First Announcement To: <geometry(a)listserv.utk.edu<mailto:geometry@listserv.utk.edu>> Dear Colleagues, We are pleased to announce the Spring 2019 Redbud Topology Conference, which will be held at the University of Oklahoma, April 26-28, 2019.

This year's conference is centered on topics in geometric group theory and low dimensional topology. Friday April 26 will be a graduate workshop with introductory talks and lightning talks by students. The main conference will take place Saturday and Sunday, April 27-28. Some funding is available; please register at the conference website by March 15, 2019 to receive full consideration. Graduate students, recent Ph.D.s, and mathematicians in underrepresented groups are especially encouraged to apply. Best regards, the Redbud organizers (Noel Brady, Matt Clay, Max Forester, Neil Hoffman, Justin Malestein, Henry Segerman, Jing Tao) ______________________ Neil R.

Today in topology seminar

Today in Topology we have Alex Casella visiting the department. His title and abstract are below. Title: Cauchy Riemann Structures Of Once-Punctured Torus Bundles Speaker: Alex Casella, Florida State University Date: Mar 5, 2019 Time: 3:30 PM Room: MSCS 509 Abstract: The Cauchy-Riemann geometry (CR in short) is modelled on the three sphere and the group of its biholomorphic transformations. In 2008, Falbel makes use of ideal triangulations to shows that the figure eight knot complement admits a (branched) CR structure. This three manifold belongs to a larger class of important three manifolds that are fiber bundles over the circle, with fiber space the once-punctured torus. In this talk we introduce the audience to these manifolds and show that almost every once-punctured torus bundle admits a (branched) CR structure. ______________________ Neil R.
