Algebraic Knot Theory

Department of Mathematics, University of Toronto, Spring 2014

Agenda. Three courses on just one theorem: With ${\mathcal {K}}$ the set of knots and ${\mathcal {A}}$ something naturally associated to knots and quite related to Lie algebras, there exists an expansion $Z\colon {\mathcal {K}}\to {\mathcal {A}}$.

Instructor: Dror Bar-Natan, drorbn@math.toronto.edu, Bahen 6178, 416-946-5438. Office hours: by appointment.

Classes. Mondays, Wednesdays, and Fridays at 10:10-11:00; Mondays and Fridays at Bahen 6180 but Wednesdays at Huron 1018. There will also be a ``HW meeting, covering no new material, on Fridays at 6:10PM at Bahen 6180.
