Computer Science/Discrete Mathematics Seminar II

The Chasm at Depth 3
10:30am|S-101

I will describe the very recent breakthrough result by Gupta, Kamath, Kayal and Saptharishi which shows that every polynomial P in n variables, of degree d which is polynomial in n, and which can be computed by a polynomial sized arithmetic circuit...

Joint IAS/Princeton University Symplectic Geometry Seminar

Contact Non-Squeezing and Rabinowitz Floer Homologhy
1:30pm|S-101

We will present joint work with Will Merry. Using spectral invariants in Rabinowitz Floer homology we present an abstract contact non-squeezing theorem for periodic contact manifolds. We then exemplify this in concrete examples. Finally we explain...

Joint IAS/Princeton University Number Theory Seminar

Regularized Periods of Automorphic Forms
4:30pm|Fine Hall 214

Following Jacquet, Lapid and Rogawski, we define a regularized period of an automorphic form on GL(n+1) x GL(n) along the diagonal subgroup GL(n) and express it in terms of the Rankin-Selberg integral of Jacquet, Piatetski-Shapiro and Shalika. This...

Mathematical Conversations

Kozai-Lidov Oscillations
6:00pm|Dilworth Room

These are a curious and only recently appreciated phenomenon in celestial mechanics, in which (for example) a planet orbiting one member of a binary star system undergoes large, slow oscillations in its orbital eccentricity and inclination. I will...
