Joint IAS/Princeton/Columbia Symplectic Geometry Seminar

Log canonical threshold and Floer homology of the monodromy
10:20am|Math 520, Columbia University

The log canonical threshold of a hypersurface singularity is an important invariant which appears in many areas of algebraic geometry. For instance it is used in the minimal model program, has been used to prove vanishing theorems, find Kahler...

Joint IAS/Princeton University Symplectic Geometry Seminar

Cellular homology, augmentations and generating families for Legendrian surfaces
4:30pm|Fine 314, Princeton University

Given a Legendrian surface in a contact one jet space, there is a local combinatorial DGA associated to the cell decomposition of the base projection of the Legendrian. The DGA is quasi-isomorphic to the Legendrian contact DGA. Using this...

Lambda-adic Waldspurger packets
Vinayak Vatsal
4:30pm|Fine 214, Princeton University

Waldspurger has shown that the genuine automorphic cuspidal representations of the metaplectic cover $S$ of $SL_2$ are divided naturally into packets, and that these packets are indexed by the cuspidal automorphic representations of $PGL_2$. We...

What is the Fukaya category?
5:00pm

The (derived) Fukaya category is a symplectic invariant developed out of work of Gromov, Floer, Fukaya, Kontsevich and Seidel that encodes the rigidity properties of Lagrangian intersections. The purpose of the talk is to discuss the construction of...
