Seminar news

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.

• The Clay Math Institute is hosting a workshop in computational arithmetic geometry September 30-October 3, organized by David Harvey, William Stein, and myself. (This is why STAGE will not meet October 1.)
• The Clay Math Institute is also hosting a workshop on rational curves and diophantine problems over function fields November 2-4. Poonen's talk on October 15 should be useful background for this.
• UCLA is hosting a conference on Selmer Groups, L-functions, and Galois Deformations March 24-29, 2008. Some funding may be available.
• MSRI (Berkeley) is hosting on workshop on modular forms and arithmetic (in honor of Ken Ribet's 60th birthday) June 28-July 2, 2008. Some funding may be available.
• The Institut de Mathématiques de Jussieu (Paris) is hosting a summer school on p-adic representations of p-adic groups July 7-12, 2008. Local expenses will be covered for 60 participants. Applications are due January 30.
• The Banff International Research Station is holding a summer school and workshop on the stable trace formula, automorphic forms, and Galois representations August 10-17 (summer school) and 17-22 (workshop), 2008. I don't have any information about funding; my past experience is that BIRS usually covers local expenses but not travel for funded participants.
• The Banff International Research Station is hosting WIN: Women in Numbers, an instructional conference for female graduate students in number theory, November 2-7, 2008. Funding is available; follow the link "conference website" from the BIRS page.

MIT will have its own number theory seminar this semester; see its web site.

Archives

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

Other local seminars

• The new 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. 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.

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.
