Special Seminar

Integrable Stochastic Particle Systems and Macdonald Processes
2:00pm|S-101

A large class of one dimensional stochastic particle systems are predicted to share the same universal long-time/large-scale behavior. By studying certain integrable models within this (Kardar-Parisi-Zhang) universality class we access what should...

Public Lecture

A Hollywood Celebrity, the `Bad Boy' of Music, and the History of Modern Wireless Communications
4:30pm|Wolfensohn Hall

Cellular telephones, GPS, radar imaging, and most other modern wireless systems would not exist without the sophisticated mathematical and digital techniques that are used to encode and decode their messages. These “spread spectrum” methods, under...

Analysis Seminar

On the Existence of Global Solutions of Certain Fluid Models
4:30pm|S-101

I will discuss recent work on the global stability of the Euler-Maxwell equations in 3D (joint work with Guo and Pausader), and of the gravity water-wave system in 2D (joint work with Pusateri).

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...

Computer Science/Discrete Mathematics Seminar II

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...
