Computer Science/Discrete Mathematics Seminar II

A Complexity Lower Bound on Algebra Isomorphisms
Jeongwan Haah
10:30am|Simonyi 101 and Remote Access

Two vector spaces of the same finite dimension are related by a linear isomorphism; that’s how the dimension is defined. Similarly, two simple subalgebras over complex numbers that are closed under conjugate transpose are related by a unitary...

Rutgers University Astrophysics Seminar

Turn down the noise, turn up the planets
John Michael Brewer
11:00am|Serin Hall Rm 330W, Rutgers and Zoom

Why haven't we found any planetary systems that look like ours? We are now in the fourth decade of detecting planets around other stars, with more than 6000 planets in 4500 systems. Detections via transit have found plenty of small planets, packed...

Analysis and Mathematical Physics

Linear Stability of Shrinking Ricci Solitons and First Eigenvalue Estimates
Huai-Dong Cao
2:30pm|Simonyi Hall 101 and Remote Access

Ricci solitons, introduced by R. Hamilton in the mid-80s, are self-similar solutions to the Ricci flow and natural generalizations of Einstein manifolds. Shrinking Ricci solitons, in particular,  model Type I singularities of the Ricci flow and...

Princeton University Dark Cosmos Seminar

Cosmological concordance from the early universe to the near field
Vera Gluscevic
4:00pm|Jadwin Hall, Joe Henry Room

Details: Cosmological observables, from the Lyman-alpha forest to the Milky Way substructure, offer unique avenues for probing dark matter and neutrino sectors. Moreover, they often reveal anomalies and tensions that could signal new physics. I will...

Amateur Astronomers Association of Princeton (AAAP) Monthly Meeting

From Sloan to Rubin: A Journey Through the Age of Sky Surveys
John Bochanski
7:30pm|Peyton Hall & Zoom

Astronomy has a rich history of surveys of the night sky, and Princeton played a major role in many of them.  In this talk, Dr. Bochanski will discuss the Vera Rubin Observatory (VRO), the largest and latest astronomical survey.  The VRO, a billion...

Mathematical Conversations

Lost in a Rough Flow
Elia Bruè
6:00pm|Simons Hall Dilworth Room

A Lipschitz velocity field gives a reassuring picture of particle motion: each starting point traces a single, well-defined trajectory. But many velocity fields arising in geometry, kinetic theory, and fluid dynamics are far rougher, and then the...

IAS Quantum Aspects of Black Holes Group Meeting

The Phase of de Sitter Higher Spin Gravity
Zimo Sun
11:00am|Bloomberg Hall Physics Library & Zoom

Abstract: I will first review the derivation of Polchinski's phase for massless higher spin fields on the sphere.

Then I will show that, in appropriate regularization schemes, the total phase of Vasiliev's higher spin gravity theory vanishes.

Institute for Advanced Study Astrophysics Seminar

Theory for innovative cosmological tests of dark matter-baryon interactions
Yacine Ali-Haimoud
11:00am|Bloomberg Lecture Hall

Among many things, dark matter could be made of new fundamental or composite particles, which may feebly interact with nuclei or electrons (“baryons”), as well as with themselves. Cosmological observables are a promising avenue to test such...
