Dual supermassive black holes at close separation revealed by the Hyper Suprime-Cam Subaru Strategic Program

Kavli Affiliate: Naoki Yasuda | First 5 Authors: John D. Silverman, Shenli Tang, Khee-Gan Lee, Tilman Hartwig, Andy Goulding | Summary: The unique combination of superb spatial resolution, wide-area coverage, and deep depth of the optical imaging from the Hyper Suprime-Cam (HSC) Subaru Strategic Program is utilized to search for dual quasar candidates. Using an […]

Topics on global analysis of manifolds and representation theory of reductive groups

Kavli Affiliate: Toshiyuki Kobayashi | First 5 Authors: Toshiyuki Kobayashi, , , , | Summary: Geometric symmetry induces symmetries of function spaces, and the latter yields a clue to global analysis via representation theory. In this note we summarize recent developments on the general theory about how geometric conditions affect representation theoretic properties on function […]

A hidden symmetry of a branching law

Kavli Affiliate: Toshiyuki Kobayashi | First 5 Authors: Toshiyuki Kobayashi, Birgit Speh, , , | Summary: We consider branching laws for the restriction of some irreducible unitary representations $Pi$ of $G=O(p,q)$ to its subgroup $H=O(p-1,q)$. In Kobayashi (arXiv:1907.07994), the irreducible subrepresentations of $O(p-1,q)$ in the restriction of the unitary $Pi|_{O(p-1,q) }$ are determined. By considering […]

On window theorem for categorical Donaldson-Thomas theories on local surfaces and its applications

Kavli Affiliate: Yukinobu Toda | First 5 Authors: Yukinobu Toda, , , , | Summary: In this paper, we prove a window theorem for categorical Donaldson-Thomas theories on local surfaces as an analogue of window theorem for GIT quotient stacks. We give two applications of our main result. The first one is a proof of […]

Cobordism Conjecture in AdS

Kavli Affiliate: Hirosi Ooguri | First 5 Authors: Hirosi Ooguri, Tadashi Takayanagi, , , | Summary: McNamara and Vafa conjectured that any pair of consistent quantum gravity theories can be connected by a domain wall. We test the conjecture in the context of the AdS/CFT correspondence. There are topological constraints on existence of an interface […]

Discovering Symbolic Models from Deep Learning with Inductive Biases

Kavli Affiliate: David Spergel | First 5 Authors: Miles Cranmer, Alvaro Sanchez-Gonzalez, Peter Battaglia, Rui Xu, Kyle Cranmer | Summary: We develop a general approach to distill symbolic representations of a learned deep model by introducing strong inductive biases. We focus on Graph Neural Networks (GNNs). The technique works as follows: we first encourage sparse […]

Anomalies, Black strings and the charged Cardy formula

Kavli Affiliate: Yuji Tachikawa | First 5 Authors: Seyed Morteza Hosseini, Kiril Hristov, Yuji Tachikawa, Alberto Zaffaroni, | Summary: We derive the general anomaly polynomial for a class of two-dimensional CFTs arising as twisted compactifications of a higher-dimensional theory on compact manifolds $mathcal{M}_d$, including the contribution of the isometries of $mathcal{M}_d$. We then use the […]
