Redbud Fall 2017 in Norman
by Hoffman, Neil 30 Oct '17

30 Oct '17

Hello everyone, On November 18th, OU is hosting the fall redbud conference. Andy and Robert are speaking. It would be great to have a strong presence out there. 1) Could you let me know if you are interested coming? 2) Would you be able to drive there? If so, how many people can you fit in your car? ______________________ Neil R.

Topology seminar this week
by Hoffman, Neil 23 Oct '17

23 Oct '17

Hello everyone, There isn't a formal topology seminar this week. But we do have two really good geometry/topology talks by Sabetta Matsumoto, a colloquium on Thursday (in the building) and a public lecture (in the union) on Friday. The details are below (abstracts on the main page): Title: Programmable Matter: using 3D printed elastic anisotropy to direct shape transformation Speaker: Elisabetta Matsumoto (Georgia Tech.) Date: Oct 26, 2017 Time: 3:30 PM Room: MSCS 514 Title: Non-euclidean virtual reality Speaker: Elisabetta Matsumoto (Georgia Tech.) Date: Oct 27, 2017 Time: 3:30 PM Room: Student Union, Rm. 416 ______________________ Neil R.

Topology lunch, seminar, dinner, lunch
by Hoffman, Neil 18 Oct '17

18 Oct '17

Hello everyone, Brandy Doleshal will be speaking in seminar today. Her title and abstract are below. We are going to Cafe 88 for lunch now, if anyone is interested. Seminar is at 3:30 and we will be going out to dinner at 5:30 at Hideaway. Everyone is welcome. Also, we will probably be going out tomorrow for lunch as well. Email me if you are interested in that. Title: Surgery equivalent primitive/Seifert knots Abstract: The primitive/primitive and primitive/Seifert knots are families of knots on the genus 2 surface with the property that surgery at the surface slopes yields lens space and Seifert fibered space surgeries. We call two knots from this class surgery equivalent if they have the same surgery at the surface slope. In this talk, we will discuss what is known about surgery equivalent primitive/Seifert knots. This is joint work with Jeffrey Meier. ______________________ Neil R.

I am speaking today
by Hoffman, Neil 11 Oct '17

Hello everyone, I am speaking today in seminar. Title: Infinite geometric triangulations of hyperbolic 3-manifolds Abstract: It is an open question if every cusped hyperbolic 3-manifold supports a geometric triangulation. More generally, one could ask which hyperbolic 3-manifolds support a infinite number number of geometric triangulations. Dadd and Duan showed that the figure 8 knot complement is one such example of this. After reviewing the background, I will discuss how to construct new examples of this phenomenon while dealing with some special cases involving two cusped manifolds. This is joint work with Jessica Purcell ______________________ Neil R.
