WEEKLY  CALENDAR
January - February 2008
Vanderbilt Mathematics


Monday 28
 1:10-2:30 pm, room 1310. Universal Algebra and Logic Seminar. Olga Sapir, Vanderbilt University. Finitely generated permutative varieties. We show that there exists an algorithm which decides whether a finite set of identities containing a permutation identity defines a variety generated by a finite semigroup or not.
3:10 pm, room 1431. Graph Theory and Combinatorics Seminar. Jonathan Wellons, Vanderbilt University. Enormous Integers in Combinatorics.
4:10-5:30 pm, room 1432. Subfactor Seminar. Paramita Das, Vanderbilt University. A new construction of subfactors from random matrix theory I. This series of talks will present the details of a new construction of subfactors due to Guionnet, Jones and Shlyakhtenko. They use a graded algebra structure of a planar algebra and certain traces inspired by random matrix theory to construct II1 factors and subfactors whose standard invariant realizes the given planar algebra. Thus they obtain an alternative proof of Popa's theorem that every (appropriate) planar algebra can be realized by a subfactor.

In the online version of this page, all underlined phrases are links; some mathematical symbols may require a browser with symbol font. Past calendars are available, as well as next week's calendar (in preparation) and a web page listing just our colloquia. We update the online calendar whenever we get information, but generally we only print paper copies on Fridays. Please submit events as early as possible, to math.calendar@vanderbilt.edu.
