|Title:||From combinatorics to geometry for knots and 3-manifolds|
|Seminar:||Department of Mathematics Colloquium|
|Speaker:||David Futer, Temple University|
|Powerful theorems of Thurston, Perelman, and Mostow tell us that almost every 3-manifold admits a hyperbolic metric, and that this metric is unique. Thus, in principle, there is a 1-to-1 correspondence between a combinatorial description of a 3-manifold and its geometry. On the other hand, only in the last couple of years have we begun to see the outlines of a concrete dictionary between combinatorial features and geometric measurements. In this vein, I will survey some recent results that explicitly relate the combinatorics of a knot diagram to geometric features of the knot complement and related closed 3-manifolds.|
