Analysis Seminar

Stationary Measures and Equidistribution on the Torus
10:30am|West Bldg. Lecture Hall

In this talk I will consider actions of non-abelian groups on n-dimensional tori, explain the notions of stiffness and stationary measures, and show how under fairly general assumptions stationary measures can be classified. A key ingredient is a...

Computer Science/Discrete Mathematics Seminar II

The Distribution of Polynomials Over Finite Fields
10:30am|S-101

I will present a recent result of Green and Tao showing the following. Let P:F^n --> F be a polynomial in n variables over F of degree at most d . We say that P is "equidistributed" if it takes on each of its |F| values close to equally often. We...

On Proving Hardness of Improper Learning from Worst-Case Assumptions
Benny Applebaum
11:15am|S-101

Learning theory, and in particular PAC learning, was introduced by Valiant in 1984 and has since become a major area of research in theoretical and applied computer science. One natural question that was posed at the very inception of the field is...
