ECH Constraints and Twist Dynamics in the Spatial Isosceles Three-Body Problem
Pedro Salomão
9:15am|Remote Access

In this talk, I will describe the global dynamics of the spatial isosceles three-body problem, using ideas from Embedded Contact Homology. For energies below the critical level, the flow admits a disk-like global surface of section bounded by the...

Informal Talk on the Quantum Soundness of the Low (individual) Degree Test: Part II
10:30am|Simonyi 101 and Remote Access

A common tool in the construction of probabilistically checkable proofs is low degree encodings. Babai, Fortnow and Lund proved the local testability of the individual low degree code, and used it to provide a multi-prover interactive proof (MIP)...

Joint IAS/PU Number Theory Seminar

Twist-Parametrized Points on Modular Curves
Filip Najman
3:30pm|Simonyi 101 and Remote Access

An important open problem is to classify rational points on all modular curves, or equivalently to classify the possible adelic Galois images of elliptic curves over Q, as envisioned in Mazur’s Program B. However, this problem is inherently infinite...

Special Campus Community Lecture

40 Years of Evolution: Darwin’s Finches
Rosemary Grant and Peter Grant
5:00pm|Simonyi Hall 101

In the “Origin of Species” Charles Darwin established the scientific basis for understanding how evolution occurs by natural selection. To explain how new species form he envisioned a three-step process involving colonization of a new area...

Geometry and Dynamics of Domains in the Cotangent Bundles of Tori
Jun Zhang
9:15am|Remote Access

In Euclidean spaces, star-shaped domains (also known as Liouville domains) are fundamental objects in modern symplectic geometry. Several important subclasses have been introduced and studied, including dynamically convex domains, geometrically...

From Fourier Restriction to Number Theory, Combinatorics, and Fractal Geometry
Dominique Maldague
9:30am|Simonyi Hall 101

Abstract: Fourier series are classically used to construct solutions to partial differential equations such as the wave and Schrödinger equations. In Fourier restriction theory, additional conditions are imposed on the frequencies of these series...

Shuffling is Universal: Statistical Additive Randomized Encodings for All Functions
Nir Bitansky
11:00am|West Lecture Hall and Remote Access

The shuffle model is a widely used abstraction for non-interactive anonymous communication. It allows $n$ parties holding private inputs $x_1,\dots,x_n$ to simultaneously send messages to an evaluator, so that the messages are received in a random...

What KdV Teaches us About Waves
Monica Visan
11:00am|Simonyi Hall 101

Abstract: In this course, we will use the Korteweg-de Vries equation as a model to understand the behavior of dispersive partial differential equations. Through this lens, we will discuss dispersion, well-posedness, and solitons.  We will also...
