Lagrangian tori, mutations and toric degenerations
6:00pm|Dilworth Room

A basic open problem in symplectic topology is to classify Lagrangian tori in a given symplectic manifold. In recent years, ideas from mirror symmetry have led to the realization that even the simplest symplectic manifolds (eg. vector spaces or...

Reading Group on Homological Mirror Symmetry and K3 Surfaces

The Yau-Zaslow conjecture / KMPS theorem
Amitai Zernik
1:00pm

In this talk I'll describe a proof of Klemm, Maulik, Pandharipande and Scheidegger of the Yau Zaslow conjecture, which equates the generating function for reduced Gromov-Witten invariants of a K3 surface with the generating function of partitions to...

Homological Mirror Symmetry (Mini-Course)

Noncommutative algebraic varieties, their properties and geometric realizations
Dmitry Orlov
10:45am

We are will discuss a notion of noncommutative and derived algebraic variety. This approach comes from a generalization of derived categories of (quasi)coherent sheaves on usual algebraic varieties and their enhancements. We are going to talk about...

Computer Science/Discrete Mathematics Seminar II

Sketching and embedding are equivalent for norms
Alex Andoni
10:30am

Sketching for distance estimation is the problem where we need to design a possibly randomized function $F$ from a metric space to short strings, such that for any points $x,y$ from the metric space, the "sketches" $F(x)$ and $F(y)$ are sufficient...
