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. ______________________ Neil R.

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. ______________________ Neil R.
