Blow up in a 3-D "toy" model for the Euler equations
4:00pm|S-101

We present a 3-D vector dyadic model given in terms of an infinite system of nonlinearly coupled ODE. This toy model is inspired by approximations to the fluid equations studied by Dinaburg and Sinai. The model has structural similarities with the...

The Dynamics of Boosting
Cynthia Rudin
11:15am|S-101

The goal of Statistical Learning Theory is to construct and understand algorithms that are able to generalize from a given training data set. Statistical learning algorithms are wildly popular now due to their excellent performance on many types of...

Joint IAS/Princeton/Rutgers Analysis Seminar

Paraproducts on Polydiscs
4:00pm|Fine Hall 214

We will describe a result which extends the classical Coifman-Meyer theorem to the multi-parameter setting of polydiscs. This is based on work recently completed jointly with Jill Pipher, Terry Tao and Christoph Thiele.

A Hodge Theoretic Approach to the Decomposition Theorem
2:30pm|S-101

Let $f:X\to Y$ be a projective map, and assume for simplicity $X$ to be smooth. The Decomposition Theorem of Beilinson, Bernstein, Deligne and Gabber states that the (derived direct image of the constant sheaf ${\bf Q}_X$ is isomorphic to a direct...

Forcing with Random Variables
10:30am|S-101

The links between propositional proof systems and bounded arithmetic (a generic name for a collection of first-order theories of arithmetic) have many facets but informally one can view them as two sides of the same thing: The former is a non...

Embedding Almost Spanning Bounded Degree Trees
11:15am|S-101

We derive a sufficient condition for a sparse graph G on n vertices to contain a copy of a tree T of maximum degree at most d on (1-\epsilon)n vertices, in terms of the expansion properties of G. As a result we show that for fixed d>=2 and 0
