Computer Science/Discrete Mathematics Seminar I

Graphs, CSPs and Codes
Madhu Sudan
11:00am|Simonyi 101 and Remote Access

A sparsification of a structure, with respect to a class of queries, produces a compressed representation of the structure while answering every query in the class approximately correctly. The seminal example of sparsification is "graph...

Princeton University Galread [Galactic/Extragalactic Reading Group]

SAGAbg I: A Near-Unity Mass Loading Factor in Low-Mass Galaxies via their Low-Redshift Evolution in Stellar Mass, Oxygen Abundance, and Star Formation Rate
Erin Kado Fong
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...

Princeton University Gravity Initiative Seminar Series

The Einstein-Euler Free Boundary Problem in Spherical Symmetry
Jared Speck
12:30pm|Princeton University, Jadwin Hall, Princeton Gravity Initiative, 4th Floor

Abstract: I will discuss work in progress with M. Disconzi on spherically symmetric solutions to the Einstein– Euler equations. The main result is local well-posedness for a class of initial data satisfying the physical vacuum condition. This is the...

Members' Colloquium

Recent Progress on the Problem of Compact Quotients
2:00pm|Simonyi 101 and Remote Access

The so-called Problem of Compact Quotients asks for which homogeneous spaces G/H there exists a discrete subgroup Gamma of G such that Gamma\G/H is a compact manifold. We will discuss this problem, and describe recent progress on it arising from...

IAS High Energy Theory Seminar

Staggered Bosons, Kahler Dirac Bosons and Supersymmetry on the Lattice
David Berenstein
2:30pm|Bloomberg Lecture Hall (IAS) & Zoom

Abstract: I will describe constructions of lattice field theories that assign a single bosonic variable to each site, rather a conjugate pair x,p. The information to realize a non-trivial dynamics is realized by non-trivial Poisson brackets between...

Computer Science/Discrete Mathematics Seminar II

Parallel Repetition for 3-Player XOR Games
10:30am|Simonyi Hall 101 and Remote Access

In a $3$-$\mathsf{XOR}$ game $\mathcal{G}$, the verifier samples a challenge $(x,y,z)\sim \mu$ where $\mu$ is a probability distribution over $\Sigma\times\Gamma\times\Phi$,  and a map $t\colon \Sigma\times\Gamma\times\Phi\to\mathcal{A}$ for a...

Institute for Advanced Study / Princeton University Joint Astrophysics Colloquium

Radiatively-cooled Magnetic Reconnection Experiments
Jack Hare
11:00am|Peyton Hall Auditorium

Abstract: In extreme astrophysical systems, such as black hole coronae and pulsar magnetospheres, the process of magnetic reconnection is significantly modified by strong radiative cooling. This cooling removes internal energy faster than it is...
