On 2-stein submanifolds in space forms

Yunhee Euh, Jihun Kim, Yuri Nikolayevsky +1

We prove that a 2-stein submanifold in a space form whose normal connection is flat or whose codimension is at most 2, has constant curvature.

Proceedings of the second MadAnalysis 5 workshop on LHC recasting in Korea

Benjamin Fuks, Pyungwon Ko, Seung J. Lee +32

We document the activities performed during the second MadAnalysis 5 workshop on LHC recasting, that was organised in KIAS (Seoul, Korea) on February 12-20, 2020. We detail the imp…

On a Canonical Quantization of 3D Anti de Sitter Pure Gravity

Jihun Kim, Massimo Porrati

We perform a canonical quantization of pure gravity on AdS3 using as a technical tool its equivalence at the classical level with a Chern-Simons theory with gauge group SL(2,R)xSL(…

On the Central Charge of Spacetime Current Algebras and Correlators in String Theory on AdS3

Jihun Kim, Massimo Porrati

Spacetime Virasoro and affine Lie algebras for strings propagating in AdS3 are known to all orders in . The central extension of such algebras is a string vertex, whose expecta…

More on Long String Dynamics in Gravity on AdS3: Spinning Strings and Rotating BTZ

Jihun Kim, Massimo Porrati

In this paper we study the classical dynamics of long strings in AdS3, generalizing our previous study, arXiv:1410.3424 [hep-th], to rotating strings and BTZ black holes. As in the…

Long String Dynamics in Pure Gravity on AdS

Jihun Kim, Massimo Porrati

We study the classical dynamics of a completion of pure AdS gravity in 3D, whose only degrees of freedom are boundary gravitons and long strings. We argue that the best regime for…

A Thermal Infrared Imaging Study of Very Low-Mass, Wide Separation Brown Dwarf Companions to Upper Scorpius Stars: Constraining Circumstellar Environments

Vanessa Bailey, Philip M. Hinz, Thayne Currie +18

We present a 3-5um LBT/MMT adaptive optics imaging study of three Upper Scorpius stars with brown dwarf (BD) companions with very low-masses/mass ratios (M_BD < 25M_Jup; M_BD / M_s…
