MONDAY, February 13, 2006

Topology/Geometry
2:30pm, Room 222
No Meeting this week

Algebra
2:30pm, Room 410
Speaker: Nadia Mazza, University of Georgia
Title of talk: The norm map and the cohomology of wreath products.
Abstract: In preparation for the upcoming mini-course on the Steenrod operations, we review the essential cohomological tools needed. Namely, we will (re-)view the notions of wreath product of finite groups, tensor induction of modules, (Evens) norm map, and cohomology of wreath products. In addition, applications and examples of the norm map will be presented.

VIGRE-Graduate Student Seminar
2:00p.m., Room 304
Speaker: Kenyon Platt, University of Georgia
Title of talk: Bird's-Eye View of Category O_S
Abstract: Given a Lie algebra g over the complex numbers, a g-module V is a complex vector space on which g acts. I will discuss briefly a certain category of g-modules called category O_S.

Colloquium
3:30pm, Room 302
Speaker: Olga Plamenevskaya, MIT
Title of talk: Heegaard Floer theory, knots, and contact structures
Abstract: Heegaard Floer theo ry is one of the most significant recent developments in low-dimensional topology. Reminiscent of gauge theory, it provides powerful invariants for 3-manifolds. Although defined via holomorphic disks, these 3-manifold invariants have an unexpected connecti on
to combinatorial knot invariants developed by Khovanov.
I will outline the construction of Heegaard Floer and Khovanov theories, as well as their relation (due to Ozsvath and Szabo). Then, I will expand these results to the world of contact topology, providing a new invariant for transversal knots, and bringing the correspondence between the two theories to a new level.
