Analysis Seminar

Conformal Invariants from Nodal Sets
3:15pm|S-101

We study conformal invariants that arise from nodal sets and negative eigenvalues of conformally covariant operators, which include the Yamabe and Paneitz operators. We give several applications to curvature prescription problems. We establish a...

Uncertainty Principle
10:30am|S-101

Informally, uncertainty principle says that function and its Fourier transform can not be both concentrated. Uncertainty principle has a lot of applications in areas like compressed sensing, error correcting codes, number theory and many others. In...

Computer Science/Discrete Mathematics Seminar I

Diffuse Decompositions of Polynomials
Daniel Kane
11:15am|S-101

We study some problems relating to polynomials evaluated either at random Gaussian or random Bernoulli inputs. We present some new work on a structure theorem for degree-d polynomials with Gaussian inputs. In particular, if p is a given degree-d...

Joint IAS/Princeton University Symplectic Geometry Seminar

Examples of Nearly Integrable Systems with Asymptotically Dense Projected Orbits
Jean-Pierre Marco
11:00am|Fine Hall 314

The talk is intended to give examples of Arnold diffusion for nearly integrable systems which are very likely to be generic. We will describe an explicit perturbation of the flat metric on the three dimensional torus which admits orbits whose...

Analytical Approach to Parallel Repetition
Irit Dinur
11:15am|S-101

We propose an “analytical” framework for studying parallel repetitions of one-round two-prover games. We define a new relaxation of the value of a game, val+, and prove that it is both multiplicative and a good approximation for the true value of...

Zeros of Zeta Functions and the Riemann Hypothesis
Anders Sodergren
6:00pm|Dilworth Room

In this talk I will present some old and new results on zeros of zeta functions. In particular, I will discuss the at first sight shocking result that there are plenty of zeta functions for which the Riemann hypothesis is false.
