WClips/Navigation

Back to WKO.
Next Meeting. Wednesday February 1, 2012, 12-2, at Bahen 4010. Peter Lee will talk about section 2.3 - finite type invariants of v- and w-braids, arrow diagrams, 6T, TC and 4T relations, and about expansions / universal finite type invariants. He may or may not discuss the (easy) construction of an expansion in the w case, and/or the (hard) construction of an expansion in the v case, which is due to him. Dror will sadly be absent.

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

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