WClips/Navigation

Back to WKO.
Next Meeting. Wednesday February 22, 2012, 12-2, at Bahen 4010. We'll cover Sections 3.1-3.4, on the basics of w-knots: what they are (along with some variants), their finite type invariants and some computational results, and the existence of an expansion.

Announcements. small circle, wide circle, UofT, LDT Blog (also here).

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