Special Year Research Seminar

Bi-\bar{Q}-structure on Shimura Varieties and Quadratic Relations Between CM Period
1:00pm|Simonyi 101

In this talk I will introduce a bi-\bar{Q}-structure on Shimura varieties, propose a hyperbolic analytic subspace conjecture (analogue of Wüstholz’s analytic subgroup theorem in this context), and explain its consequence on quadratic relations...

Joint PU/IAS Number Theory

A Cubic Fourfold with Sextic Dual
Victor Wang
3:30pm|*Princeton University, Fine 214*

I will report on joint work in progress with Tim Browning and Ritabrata Munshi, concerning the use of the circle method to count rational points on a particular cubic hypersurface in six variables. This problem lies at the square-root barrier, and I...

Computer Science/Discrete Mathematics Seminar I

A General Quantum Duality for Representations of Groups with Applications to Quantum Money, Lightning, and Fire
Barak Nehoran
11:00am|Simonyi Hall 101 and Remote Access

Note: This talk will involve quantum computing, cryptography, and representation theory, but no background in any of these will be necessary to understand it. I'll introduce everything from the basics.

Aaronson, Atia, and Susskind (2020) established...

Members' Colloquium

Homological Stability of Moduli Spaces
1:30pm|Simonyi 101 and Remote Access

Homological stability has emerged over the past decades as an organizing principle in topology and beyond. Broadly speaking, many sequences of moduli spaces exhibit the striking phenomenon that their homology stabilizes as the underlying complexity...

Computer Science/Discrete Mathematics Seminar II

List Decoding: Algebraic and Combinatorial
10:30am|Simonyi 101 and Remote Access

In the theory of error-correcting codes, list decoding allows a decoder to output a list of candidates when attempting to remove noise from a corrupted input. The constructions and algorithms for such list decodable codes has had numerous...

Analysis and Mathematical Physics

A Counterexample to the Berger-Coburn Conjecture
Sam Looi
2:30pm|Simonyi Hall 101 and Remote Access

Berger and Coburn conjectured that a Toeplitz operator on Bargmann--Fock space is bounded if and only if the heat transform of its symbol at time $t=1/4$ is bounded, the borderline time singled out by the Weyl calculus under the Bargmann transform...
