Revision as of 02:00, 13 August 2008


These are weekly over-lunch knot theory meetings held at the University of Toronto.

Summer Schedule

Tentatively, this summer (2008) we will hold meetings on April 16 and 23, May 21 and 28, June 4, 11, and the whole week of June 16-20, July 2 and 30, August 6 and 27 and September 3 and 10.

Future Agendas Queue

The below are possible agendas for future meetings, roughly ordered by priority. Though the general principle will remain, that the whims of the moment always trump long term planning.

  • Lucy Zhang on topological quantum computation.
  • Infinitesimal Artin - derivations on free Lie algebras.
    • Derivations, tangential derivations, special derivations (see BBS/Alekseev-080116-162451.jpg).
    • Drinfel'd's theorem on special derivations (see Drinfel'd's On quasitriangular Quasi-Hopf algebras and a group closely connected with \operatorname{Gal}(\bar{{\Bbb Q}}/{\Bbb Q}), Leningrad Math. J. 2 (1991) 829-860, though I wouldn't be surprised if the theorem is actually older).
    • Can you prove that {\mathcal A}^\mbox{hor} injects into {\mathcal A}^\mbox{trees}?
    • The VS structure on several kinds of algebras of derivations. As always, can you find associators?
    • The Alekseev-Torossian "divergence" (BBS/Alekseev-080121-093327.jpg).
  • Homotopy invariants of pure tangles, their Artin theory and their infinitesimal theory.
  • Bracelets and the Goussarov filtration.
  • Will anybody be interested in reporting on A Sequence of Degree One Vassiliev Invariants for Virtual Knots, arXiv:0803.0754, by Allison Henrich?
