Almost Sharp Sharpness for Boolean Percolation
Barbara Dembin
11:15am|Simonyi 101 and Remote Access

We consider a Poisson point process on $R^d$ with intensity lambda for $d>=2$. On each point, we independently center a ball whose radius is distributed according to some power-law distribution mu. When the distribution mu has a finite d-moment...

Hofer's Geometry and Braid Stability
Marcelo Alves
9:15am|Remote Access

The Hofer’s metric dH is a remarkable bi-invariant metric on the group of Hamiltonian diffeomorphisms of a symplectic manifold. In my talk, I will explain a result, obtained jointly with Matthias Meiwes, which says that the braid type of a set of...

A Motivic Circle Method
4:30pm|Princeton University, Fine Hall 224

The circle method has been a versatile tool in the study of rational points on hypersurfaces. More recently, a version of the method over function fields, combined with spreading out techniques, has led to information about moduli spaces of rational...

Rational and Integral Points on Elliptic Curves
6:00pm|Birch Garden, Simons Hall

We discuss some questions that arise when studying rational and integral points on curves, especially elliptic curves. For example, for a "random" such curve, how many rational points should it have? This will be a talk suitable for a general math...

Classical Turbulence as Quantum Geometry
Alexander Migdal
4:30pm|Simonyi 101 and Remote Access

The loop equation for circulation PDF as functional of the loop shape is derived from the Hopf equation. This equation is $\textbf{exactly}$ equivalent to the Schrödinger equation in loop space, with viscosity playing the role of Planck's constant...

Additive Energy of Regular Measures in One and Higher Dimensions, and the Fractal Uncertainty Principle
3:00pm|Simonyi 101 and Remote Access

We obtain new bounds on the additive energy of (Ahlfors-David type) regular measures in both one and higher dimensions, which implies expansion results for sums and products of the associated regular sets, as well as more general nonlinear functions...

Toward Classifying Reducts of the Complex Field
Chieu-Minh Tran
4:00pm|Simonyi 101 and Remote Access

We discuss some recent progress on the model-theoretic problem of classifying the reducts of the complex field (with named parameters and up to interdefinability). The tools we use include Castle’s recent solution of the Restricted Trichotomy...

Exponential Mixing and Fractal Uncertainty
Osama Khalil
2:00pm|Simonyi 101 and Remote Access

The Bowen-Ruelle conjecture predicts that geodesic flows on negatively curved manifolds are exponentially mixing with respect to all their equilibrium states. In a breakthrough in '98, Dolgopyat pioneered a method rooted in the thermodynamic...
