Hello everyone,

Just a reminder that Robert is presenting in topology seminar today. This kicks off a rather busy semester for seminar. Right now, we only have April 9 and 16 open.

Robert's title and abstract are below:

Title: Polynomial pinching

Speaker: Robert Haraway,

Oklahoma State University

Date: Jan 22, 2019

Time: 3:30 PM

Room: MSCS 509

Abstract: In joint work with Neil Hoffman, we use the algorithm of Agol, Hass, and Thurston to give a construction of an ideal triangulation of the exterior of a normal surface S in a triangulation T that is polynomial in space and time of order |T| ∗ log |S|, where |T| is the number of tetrahedra and |S| is the total weight |S ∧ T|. (part 1 of 2)
