Joint IAS/Princeton/Montreal/Paris/Tel-Aviv Symplectic Geometry Zoominar

Three 20-min Research Talks
Yash Deshmukh, Lea Kenigsberg and Thomas Massoni
9:15am|Remote Access

Yash Deshmukh (Columbia University): Moduli Spaces of Nodal Curves from Homotopical Algebra

I will discuss how the Deligne-Mumford compactification of curves arises from the uncompactified moduli spaces of curves as a result of some algebraic...

Princeton University Galread [Galactic/Extragalactic Reading Group]

Star Formation Laws and Efficiencies across 80 Nearby Galaxies
Jiayi Sun
11:00am|Zoom and Peyton Hall, Grand Central

Each week, we hold a relatively informal seminar/discussion series with an emphasis on extra-galactic and large-scale structure astrophysics.

During Galread a leader/visitor presents a recent paper to the discussion group. The PDF of the paper is...

Computer Science/Discrete Mathematics Seminar I

Algorithmic Stochastic Localization for the Sherrington-Kirkpatrick Model
Mark Sellke
11:15am|Simonyi Hall 101 and Remote Access

Sampling from high-dimensional, multimodal distributions is a computationally challenging and fundamental task.  This talk will focus on a family of random instances of such problems described by random quadratic potentials on the hypercube known as...

Princeton University Extrasolar Planet Discussion Group

Resonant Excitation of Planetary Eccentricity due to a Dispersing Eccentric Protoplanetary Disk: A New Mechanism of Generating Large Planetary Eccentricities
Jiaru Li
12:00pm|Zoom and Peyton Dome Rm, Princeton University

I will present a new mechanism of generating large planetary eccentricities. This mechanism applies to planets within the inner cavities of their companion protoplanetary disks. A massive disk with an inner truncation may become eccentric due to non...

Institute for Advanced Study/Princeton University Early Universe/Cosmology Lunch Discussion

Topic 1: Tidal deformability from scattering and the role of analytic continuation Topic 2: TBA
Gaston Creci Keinbaum and Heyang Long
12:30pm|West Building Seminar

Abstract 1: The tidal response of a compact object is a key gravitational-wave observable encoding information about its interior. This link is subtle due to the nonlinearities of general relativity. I will show that considering a scattering process...

Members' Colloquium

An Introduction to Random Surfaces
Scott Sheffield
2:00pm|Simonyi Hall 101 and Remote Access - see Zoom link below

The theory of "random surfaces" has emerged in recent decades as a significant field of mathematics, lying somehow at the interface between geometry, probability, and mathematical physics. I will give a friendly (I hope) colloquium-level overview of...

Joint IAS/Princeton University Symplectic Geometry Seminar

Computing Embedded Contact Homology in the Morse-Bott Setting using Cascades
Yuan Yao
4:00pm|Simonyi 101 and Remote Access

I will first give an overview of ECH. Then I will describe how to compute ECH in the Morse-Bott setting a la Bourgeois. I will discuss some classes of examples where this approach works. Finally I will sketch the gluing results that allow us to...

Computer Science/Discrete Mathematics Seminar II

The Hypergraph Container Method, Partition Containers, and Algorithmic Applications
Or Zamir
10:30am|Simonyi Hall 101 and Remote Access

The recently-discoverd Hypergraph Container Method (Saxton and Thomason, Balogh, Morris and Samotij), generalizing an earlier version for graphs (Kleitman and Winston), is used extensively in recent years in extremal and probabilistic combinatroics...
