Special Year Learning Seminar

On a Problem of Polya and Some of its Evolutions
Umberto Zannier
2:00pm|Simonyi 101

Around 1921 Polya asked about the algebraicity of the indefinite integral of an algebraic function, in terms of the integrality of the coefficients in a power-series expansion. Polya nicely answered the special case of rational functions, using...

Gabriel Goldberg
4:00pm|Simonyi Hall 101

Abstract. This talk will survey the Ultrapower Axiom (UA), an amalgamation principle in set theory that has emerged as a common structural feature of three very different set-theoretic frameworks: canonical inner models, determinacy axioms, and very...

IAS Quantum Aspects of Black Holes Group Meeting

Averaging over N
11:00am|Bloomberg Hall Physics Library

Abstract:  "Wormholes" seem to describe ensemble averages of some kind, but in realistic models of holography, like AdS_4xS^7, it seems there isn't anything to average over, except, in some examples, a single integer N. Is "averaging over N" enough...

Local Intertwining Relation
Sug-Woo Shin
3:30pm|Simonyi 101 and Remote Access

The local intertwining relation (LIR) is an identity that gives precise information about the action of normalized intertwining operators on parabolically induced representations. It plays a central role in Arthur’s endoscopic classification for...

The Search for Axion Dark Matter
Benjamin Safdi
4:00pm|Jadwin Hall A-10

Abstract: Axions are some of the best-motivated beyond the Standard Model particle candidates at present. These ultralight particles may account for the cosmological dark matter and explain other outstanding problems in nature, such as the strong-CP...
