Upcoming Research Lecture: Dr. Pavel Etingof to speak on Friday, June 11, 2010

May 28th, 2010

Please join us on Friday, June 11, 2010 as Dr. Pavel Etingof of MIT will be giving a lecture about D-modules on Poisson varieties and Poisson traces. We will be serving coffee, tea, and cookies starting at 3:30pm and the lecture will begin at 4:00pm.  The lecture will be held in our studio classroom at 929 Massachusetts Avenue Suite #102 in Cambridge. The abstract is listed below and we look forward to seeing you!

Abstract: Let V be an affine symplectic algebraic variety over C, and G a finite group of automorphisms of V (for example, V is a symplectic vector space, and G is a subgroup of Sp(V)). Let A be the algebra of regular functions on V/G, and E be the space of linear functionals on A which are invariant under Hamiltonian vector fields on V/G (so called Poisson traces). It turns out that E is finite dimensional.  I will explain how to prove and generalize this statement, using the theory of D-modules, and will also describe some applications to noncommutative algebra. This is joint work with Travis Schedler.

The Worldwide Center of Mathematics, www.centerofmath.org , is located midway between Harvard and Central Squares, at 929 Massachusetts Avenue, Cambridge, MA, in Suite #102. Travel to the Center by public transportation is easy via the #1 bus, or by taking the subway (the T) to Central Square, and walking for 10 minutes. Suite #102 is located on floor 01.

All attendees will need to sign a release form, as the lecture will be recorded for distribution on the Web.

Upcoming Talk: Residual properties of 3-manifold groups

March 2nd, 2010

Announcing an upcoming talk by Thomas Koberda from Harvard University on Friday, March 12, 2010 at 4pm.  Please join us for coffee, tea, cookies at 3:30pm.  Our office is located in Cambridge, Massachusetts, 929 Mass Ave, Suite 102.

Abstract: Let M be a compact 3-manifold and G its fundamental group. We are interested in understanding the algebraic structure of G. Some aspects of its algebraic structure are the different types of quotients G might admit. We will discuss families of proper quotients of G such that each element of G survives in one of the quotients. In particular, we will be considering pgroup quotients and torsion-free nilpotent quotients of G. Residual properties of 3-manifold groups are of interest because they are key in answering certain questions about the geometry of 3-manifolds.

The Worldwide Center of Mathematics, www.centerofmath.org , is located midway between Harvard and Central Squares, at 929 Massachusetts Avenue, Cambridge, MA, in Suite #102. Travel to the Center by public transportation is easy via the #1 bus, or by taking the subway (the T) to Central Square, and walking for 10 minutes. Suite #102 is located on floor 01, which is distinct from floor 1.

Hope to see you there!
