WClips/Navigation

Back to WKO.
Next Meeting. On Wednesday April 4, 2012, 12-2, at Bahen 4010 we will return to the main sequence and talk about Section 3.7, "the Alexander polynomial", and perhaps start with Section 3.8, on the proof of the Alexander theorem.

Announcements. small circle, wide circle, UofT, LDT Blog (also here). Email Dror to join our mailing list!

Resources. How to use this site, Dror's notebook, blackboard shots.
