Seminar news

I am not planning to organize STAGE during the 2009-2010 academic year. I will have more to say about what happens next year later in the term.

Mark Behrens is organizing a K-theory lunch seminar this semester, on the interplay between arithmetic geometry (specifically crystalline cohomology) and homotopy theory (specifically algebraic K-theory). It meets Tuesdays and Thursdays 11:30-1, room TBA.

This semester's topics in number theory course (18.787), on trace formulas and automorphic forms, will meet Tuesdays and Thursdays 1-2:30 in room 8-119.

Note that there is a separate mailing list for the MIT number theory seminar; that list also has a separate web page. This list will be used also for announcements about the BC-MIT number theory seminar.

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.

• Next year's Arizona Winter School will be held March 14-18 in Tucson; the topic is quadratic forms. The speakers will be Manjul Bhargava, John Conway, Noam Elkies, Jonathan Hanke, and Raman Parimala. As usual, funding is available for graduate students.
• There will be a spring school on p-adic methods in arithmetic geometry at Hebrew University, March 29-April 7.
• There will be a summer school on Diophantine geometry June 15-26 in Rennes, France. I have no information about funding.
• The Clay Mathematics Institute will be sponsoring a summer school on Galois representations at the University of Hawaii, June 15-July 10. Funding is available; the deadline is February 15.
• There will be a summer school on computational aspects of automorphic forms June 22-July 3 in Montréal. I have no information about funding.
• The Park City Mathematics Institute program for 2009 will be on arithmetic of L-functions, and takes place June 28-July 18. Funding is available for graduate students; applications are due January 28.
• The International Centre for Theoretical Physics (Trieste) will hold a school and workshop on p-adic analysis and applications August 31-September 18. I have no information about funding.

Archives

I have archived the home pages from the spring 2004, fall 2004, spring 2005, fall 2005, spring 2006, fall 2006, spring 2007, fall 2007, spring 2008, and fall 2008 semesters.

Other local seminars

• The MIT number theory seminar is a research seminar in number theory.

• The Baby Algebraic Geometry Seminar (BAGS) is a joint Harvard-MIT graduate seminar in algebraic geometry; it is distinguished from STAGE by being more focused on "classical" algebraic geometry and less on arithmetic. (There is however a sizable overlap in both topics and audience.) It is scheduled in conjunction with the joint Harvard/MIT algebraic geometry seminar, with its location correspondingly rotating between Harvard and MIT.

• The Boston University algebra seminar is in fact a research seminar in number theory. (The easiest way to the BU math department is probably to walk. Allow 25-30 minutes.)

• In prior semesters, BU has also 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.
