PU High Energy Theory Seminar

Aspects of T Tbar Deformation and the Kernel Formula
Aki Hashimoto
2:30pm|Jadwin Hall, PCTS Room 407

Abstract: In this talk, I will review a simple derivation of an integral kernel formula for the partition function of T Tbar deformed CFT based on the holographic single trace T Tbar deformation and its generalization to J Tbar and J Jbar...

Joint IAS/Princeton Arithmetic Geometry Seminar

On De Rham Flip-Flopping in Dual Towers
3:30pm|Simonyi Hall 101 and Remote Access

We will discuss de Rham and Hyodo-Kato flip-flopping for dual towers of rigid analytic spaces. The main tools are comparison theorems expressing the two cohomologies as pro-étale cohomologies of corresponding relative period sheaves that, by...

Computer Science/Discrete Mathematics Seminar II

New Derandomized Agreement Testers
10:30am|Simonyi Hall 101 and Remote Access

Agreement testing (aka direct product testing), checks if consistent local information reveals global structure. Beyond its theoretical connections to probabilistic checkable proofs (PCPs), constructing agreement testers is a fundamental...

Institute for Advanced Study / Princeton University Joint Astrophysics Colloquium

How well can we estimate stellar ages?
Jamie Tayar
11:00am|Peyton Hall Auditorium

Good estimations of stellar ages are important for a wide range of science cases, from understanding the evolution and habitability of exoplanetary systems to tracking back the cosmic history of our own and other galaxies. These ages, however, are...

Condensed Learning Seminar

Six Functors
Juan Esteban Rodriguez Camargo
2:30pm|Simonyi Hall 101

Define the category of solid quasi-coherent sheaves $\mathcal{D}_\blacksquare(X)$ on a rigid-analytic varity $X$. Show that this assignment comes with a natural $6$-functor formalism. Finally, prove the Grothendieck--Serre duality in the rigid...

Princeton University Dark Cosmos Seminar

Near-field Cosmology with Stellar Streams
Nora Shipp
4:00pm|Jadwin Hall, Joe Henry Room

Abstract: Stellar streams, the tidal remnants of globular clusters and dwarf galaxies orbiting throughout the Milky Way’s halo, are some of the most powerful tools in the study of near-field cosmology. In particular, they are sensitive probes of the...

IAS Physics Group Meeting

Gravitational Wave Measurements with Pulsar Timing Arrays
11:00am|Bloomberg Lecture Hall (IAS)

Abstract: Pulsar timing arrays (PTAs) consist of a set of regularly monitored millisecond pulsars with extremely stable rotational periods. The arrival time of pulses can be altered by the passage of gravitational waves (GWs) between them and the...
