Agenda. Learn about the surprising relation between the easily deformed (topology) and the most rigid (algebra).
Ambition. Get to the Wirtinger presentation of the fundamental group of knot complements and to the definition of the Alexander polynomial as the order ideal of the first homology of the universal Abelian cover of a knot complement. Both of these goals are just a bit too far, yet they can serve as perfect motivators for all that isn't too far.
Instructor. Dror Bar-Natan, drorbn@math.toronto.edu (for course administration matters only; math on email is slow and prone to misunderstandings, so I generally avoid it). Office: Bahen 6178.
Teaching Assistant. Charlie Wu, charliec.wu@mail.utoronto.ca.
Classes. Mondays 10-11am and Tuesdays 4-6pm, at Bahen 6183.
Office Time. Mostly Thursdays 5:00-6:30pm at Bahen 6178 and online at https://drorbn.net/vchat.
Text. Mostly Alan Hacther's Algebraic Topology, but also several specialized sources for specialized topics.
