Marston Morse Lectures

What is Special About Polynomials? (Perspectives from Coding theory and Differential Geometry)
2:00pm|S-101

Polynomials are a special class of functions. They are useful in many branches of mathematics, often in problems which don't mention polynomials. We discuss two examples: polynomials in error-correcting codes and polynomials in geometric...

Marston Morse Lectures

Unexpected Applications of Polynomials in Combinatorics
2:00pm|S-101

In 2007, Zeev Dvir shocked experts by giving a one-page proof of the finite field Kakeya problem. The new idea in the proof was to introduce high degree polynomials into a problem about points and lines. This idea has led to progress on several...

Computer Science/Discrete Mathematics Seminar II

Sensitivity Versus Block Sensitivity, I
10:30am|S-101

There are two important measures of the complexity of a boolean function: the sensitivity and block sensitivity. Whether or not they are polynomial related remains a major open question. In this talk I will survey some known results on this...

Random Matrices, Dimensionality Reduction, and Faster Numerical Linear Algebra Algorithms
2:00pm|S-101

A fundamental theorem in linear algebra is that any real n x d matrix has a singular value decomposition (SVD). Several important numerical linear algebra problems can be solved efficiently once the SVD of an input matrix is computed: e.g. least...

Intractability in Algorithmic Game Theory
Tim Roughgarden
11:15am|S-101

We discuss three areas of algorithmic game theory that have grappled with intractability. The first is the complexity of computing game-theoretic equilibria, like Nash equilibria. There is an urgent need for new ideas on this topic, to enable...

Joint IAS/Princeton University Symplectic Geometry Seminar

Lagrangian Caps in High-Dimensional Symplectic Manifolds
1:30pm|Fine Hall 322

I will present a recent result (joint with Yakov Eliashberg) demonstrating the existence of exact Lagrangian cobordisms with a loose Legendrian in the negative end, in all dimensions greater than 4. In particular, we show that there exists a...
