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.

• This year's Arizona Winter School is on special functions and transcendence, and takes place March 15-19.
• UCLA is hosting a conference on Selmer Groups, L-functions, and Galois Deformations March 24-29, 2008. Some funding is avaliable; the deadline for applying is January 18.
• 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 is available; the deadline for applying is May 9.
• 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, a semi-instructional conference for female graduate students in number theory, November 2-7, 2008. Funding is available but space is limited; the deadline for applying is March 1. (Follow the link "conference website" from the BIRS page.)

Archives

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