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 list of conferences in number theory. (Suggestions for either list are welcome!) To wit:

• The Clay Math Institute is sponsoring a summer school; the deadline for funding has passed.

• MSRI is hosting a summer graduate workshop on computational number theory, organized by William Stein.

Archives

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

Other local seminars

• The Baby Algebraic Geometry Seminar (BAGS) is an MIT graduate seminar in algebraic geometry (not as arithmetically oriented as STAGE); I don't know yet where its home page will be next semester.

• 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 or the #1 bus from 77 Mass. Ave., 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.

• The Brandeis Fellowship of the Ring is an algebra seminar which includes some number theory. Unfortunately it's a bit hard to get to from here without driving.

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.) Beware that these have not yet been updated from last semester, but they're 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.
