Geometric Langlands Seminar
Normally the seminar meets on Mondays and/or Thursdays in
room E206, 4:30
pm--??, where "??" denotes the time when we get tired (e.g., 7:30 pm).
Here are the email
announcements for the current academic year and
information for visitors.
Some texts related to the
talks at the seminar
and Footboards. You might have heard these words mentioned on
the seminar. If you ever wondered what they meant, here's an

the seminar by M. Boyarchenko in the spring of 2006. The notes contain
no original results, and probably do contain lots of mistakes.
