Hello Topologist and Friends of Topology,

We are please to have Topology Seminar this Thursday (MSCS 514 at 3:30) given by Maggy Tomova form The University of Iowa.

Title: Obtaining topological information from knot diagrams

Abstract: Knots and links are most easily visualized via a projection diagram. However, obtaining topological and geometric information from such a presentation has proven to be difficult. In this talk I will discuss conditions on the diagram that allow us to show that any closed essential surface in the knot complement has high genus. This is joint work with Ryan Blair and David Futer.
