MIT STAGE: Seminar on Topics in Arithmetic, Geometry, Etc.

MIT STAGE (Seminar on Topics in Arithmetic, Geometry, Etc.)
Spring 2007: Mondays 1-3, room 4-149

This is the home page of STAGE, the Seminar on Topics in Arithmetic, Geometry, Etc. To get on (or off) the seminar mailing list, contact me (Kiran Kedlaya).

Seminar news

On May 14, we meet 12-1 and 1-2, instead of 1-2 and 2-3, to avoid conflicting with Mori's talk at the Clay Research Conference. (The talks by Kisin and Taylon on May 15 may also be of interest.) The May 14 meeting is still in the usual room 4-149; on May 21, we meet instead in 4-163, but back at the usual times.

Conference news

I like to collect news about conferences of interest to students in arithmetic geometry. Note that I also maintain an overall wiki list of conferences in number theory.

William Stein has announced SAGE Days 4 for June 12-17, at U. Washington.
There is a NATO summer school on higher-dimensional geometry over finite fields June 25-July 6 in Göttingen.
CIRM (Luminy) is hosting a summer school on Serre's conjecture July 9-20.
MSRI's summer graduate workshop this year is on deformation theory and moduli spaces.
I'm co-organizing a workshop on (computational aspects of) L-functions and modular forms at AIM (Palo Alto), July 30-August 3.
McMaster University (Hamilton, Ontario) is hosting a summer school on Iwasawa theory August 9-13. It looks like their model is the Arizona Winter School: the intended audience is graduate students, some of whom will work on projects led by one of the four lecturers, and will present the projects at the end of the school.

Other local seminars

The Baby Algebraic Geometry Seminar (BAGS) is a graduate seminar in algebraic geometry; it is distinguished from STAGE by being more focused on "classical" algebraic geometry and less on arithmetic. BAGS, like STAGE, enjoys strong crossover attendance from Harvard. Indeed, lately it has been scheduled right after the joint Harvard/MIT algebraic geometry seminar, with its location correspondingly rotating between Harvard and MIT.
This semester, Izzet Coskun is also organizing a graduate seminar on the Minimal Model Program.
The Boston University algebra seminar is in fact a (research-level) number theory seminar by another name. (The easiest way to the BU math department is probably to walk. Allow 25-30 minutes.)
BU also has had a student seminar in number theory and algebraic geometry; I expect this will happen again in future.
The Harvard number theory seminar does not have a separate home page; you can see upcoming talks listed on the math department seminar listing. (Take the red line from Kendall, in which case allow 20 minutes. Or walk up Mass. Ave., in which case allow 35 minutes.)
At any given moment, there are typically several informal graduate seminars in existence at Harvard, but they're so informal as to ordinarily not have web pages.

Miscellanea

Check out the web page for the McGill seminar on cohomology theories from the 2003-2004 academic year. They have some notes posted which may be of interest.

I'm collecting a list of references for topics that come up in the seminar (see also the McGill page), and a list of potential topics. (The latter is not to be confused with "topics not yet scheduled", which are the ones I am actively looking to include.) This list is now quite old, but possibly still useful.

Some information about the seminar (some of which is now dated) is contained in the introductory email that I sent out to the mailing list on December 23, 2003, and the followup email that I sent on January 6, 2004.

This page is maintained by Kiran Kedlaya; it was shamelessly copied from Jason Starr's page, which in turn was shamelessly copied from Ravi Vakil's page, which in turn was shamelessly copied from Pasha Belorousski's page at the University of Michigan.
