Computer Science/Discrete Mathematics Seminar I

Computationally Sound Proofs of Network Properties
Rotem Oshman
11:00am|Simonyi 101 and Remote Access

In distributed certification, our goal is to certify that a network has a certain desired property, e.g., the network is connected, or the internal states of its nodes encode a valid spanning tree of the network. To this end, a prover generates...

Princeton University Galread [Galactic/Extragalactic Reading Group]

AGN properties of ∼1 million member galaxies of galaxy groups and clusters > at z < 1.4 based on the Subaru Hyper Suprime-Cam survey.
Justin Myles
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...

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

Exploring Tidal Effects: A New Perspective From Effective Field Theory
Zihan Zhou
12:30pm|IAS, West Seminar Room

Tidal effects serve as a useful tool to study compact objects. In this talk, I will present how the worldline effective field theory (EFT) can be applied to examine the tidal responses of compact objects. This approach offers a robust framework for...

Princeton University Gravity Initiative Seminar Series

High-precision waveforms with the small-mass-ratio limit
Scott Hughes
12:30pm|Princeton University, Jadwin Hall, Princeton Gravity Initiative, 4th Floor & Zoom

Abstract: Current gravitational-wave detectors are being upgraded, and plans are developing for future detectors with greater sensitivity over broader frequency bands.  As instruments improve and develop, more cycles of sources’ gravitational...

Symplectic Geometry Seminar

The Shape Invariant for Toric Domains.
Richard Hind
12:30pm|Simonyi 101 and Remote Access

We discuss the shape invariant, a sort of set valued symplectic capacity defined by the Lagrangian tori inside a domain of $R^4$. Partial computations for convex toric domains are sometimes enough to give sharp obstructions to symplectic embeddings...

Members' Colloquium

Sum-of-Squares Proofs, Efficient Algorithms, and Applications
2:00pm|Simonyi 101 and Remote Access

Any non-negative univariate polynomial over the reals can be written as a sum of squares.  This gives a simple-to-verify certificate of non-negativity of the polynomial. Rooted in Hilbert's 17th problem, there's now more than a century's work that...

Joint IAS/Princeton Arithmetic Geometry Seminar

Towards a Unified Theory of Canonical Heights on Abelian Varieties
Padmavathi Srinivasan
3:30pm|Simonyi Hall 101 and Remote Access

p-adic heights have been a rich source of explicit functions vanishing on rational points on a curve. In this talk, we will outline a new construction of canonical p-adic heights on abelian varieties from p-adic adelic metrics, using p-adic Arakelov...
