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...

Members’ Seminar

Homological versus Hodge-theoretic mirror symmetry
2:00pm

I'll describe joint work with Sheel Ganatra and Nick Sheridan which rigorously establishes the relationship between different aspects of the mirror symmetry phenomenon for Calabi-Yau manifolds. Homological mirror symmetry---an abstract, categorical...

Computer Science/Discrete Mathematics Seminar I

Quantifying tradeoffs between fairness and accuracy in online learning
Aaron Roth
11:15am

In this talk, I will discuss our recent efforts to formalize a particular notion of “fairness” in online decision making problems, and study its costs on the achievable learning rate of the algorithm. Our focus for most of the talk will be on the...
