Maggy TomovaProfessor and Chair of the Department of Mathematics, The University of Iowa.Field: Topology |
SeminarDate and Time: Monday, November 30th at 2:00 PM Zoom link: TBA Talk: Generalizing classical invariants to achieve additivity Abstract: In this talk, I will discuss joint work with Scott Taylor where we generalize tunnel number, bridge number, and width of knots to find invariants that have wider applicability in the study of knots, graphs, and 3-manifolds.

ColloquiumDate and Time: Monday, November 30th at 4:00 PM Zoom link: TBA Talk: Properties of Knots in Thin Position Abstract: Width is a knot invariant introduced by Gabai in the 80's as an ad hoc method to study foliations of 3-manifolds. In this talk, I will discuss some of the uses of thin position that have been developed in the last 30 years as well as some cool results about the behavior of thin position and how it compares to other knot invariants.
