The first ANNOUNCEMENT, November 1, 2005
Skein modules, Khovanov homology and Hochschild homology
 December 9-11, 2005
The 21th Conference on Knot Theory and its Ramifications
George Washington University, Washington, DC

You are cordially invited to attend our Knots in Washington XXI conference.
Skein modules, Khovanov homology and Hochschild homology.

Plenary speakers include: Dror Bar-Natan, Mikhail Khovanov (two talks), Lev Rozansky, Paul Turner, Ben Webster (Distinguish graduate student talk).
This regional conference is held every semester, in various locations in the Washington area
(see the main KIW page ).

The conference will take place at George Washington University.

We plan six plenary talks - 50 minutes long, and 20 minutes long research talks.

You are cordially invited to participate in this and future meetings.

We will start on December 9, 1:00 pm with the talk by Mikhail Khovanov.
It will take place in the room 113 of the building 1957 E street (GWU).

If you plan to attend please contact one of the organizers. No registration fee!
