Hello everyone,
Eric Towers is speaking in topology seminar today.
He will be discussing his own work. His title and abstract are below:
Title:Building censuses of links in lens spaces
Speaker: Eric Towers, Oklahoma State
Date: Feb 25, 2020
Time: 3:30 PM
Room: MSCS 509
Abstract: The theory and automation of the exhaustive study of links (including knots) in ^3 is understood. Extending these methods to completely enumerate links in specified ambient spaces other than S^3 is less well understood. For any fixed lens space L(p, q), we describe a method for producing all links with a prescribed complexity in the ambient L(p, q). We demonstrate progress in software to automate the enumeration and feature extraction of lens space link complements and their fillings.

Hello Everyone,
We have Martin Bobb visiting today from UT.
His title and abstract are below:
Title: Flats in compact convex projective manifolds
Speaker: Date: Time: Room:
Martin Bobb, University of Texas
Feb 11, 2020
3:30 PM MSCS 509
Abstract: Convex projective structures on manifolds are a rich generalization of hyperbolic structures. One key difference is that a convex projective manifold may have flat substruc- tures. We will discuss some first examples of convex projective geometry, and then describe a natural decomposition of compact convex manifolds along their codimension-1 flats. This generalizes a result of Benoist, which states that a compact convex projective 3-manifold geometrically JSJ-decomposes into cusped hyperbolic manifolds.
