Kavli Affiliate: Tomoyuki Abe | First 5 Authors: Tomoyuki Abe, , , , | Summary: Bivariant theory is a unified framework for cohomology and Borel-Moore homology theories. In this paper, we extract an $infty$-enhanced bivariant homology theory from Gaitsgory-Rozenblyum’s six functor formalism. | Search Query: ArXiv Query: search_query=au:”Tomoyuki Abe”&id_list=&start=0&max_results=10 Read More
Kavli Affiliate: Yasunori Nomura | First 5 Authors: Chitraang Murdia, Yasunori Nomura, Pratik Rath, , | Summary: Motivated by the understanding of holography as realized in tensor networks, we develop a bulk procedure that can be interpreted as generating a sequence of coarse-grained holographic states. The coarse-graining procedure involves identifying degrees of freedom entangled at […]
Kavli Affiliate: Satoshi Shirai | First 5 Authors: Masahiro Ibe, Shin Kobayashi, Yuhei Nakayama, Satoshi Shirai, | Summary: Recently, the XENON1T collaboration reported an excess in the electron recoil energy spectrum. One of the simplest new physics interpretation is a new neutrino-electron interaction mediated by a light vector particle. However, for the parameter region favored […]
Kavli Affiliate: Tadayuki Takahashi | First 5 Authors: Ryota Tomaru, Chris Done, Ken Ohsuga, Hirokazu Odaka, Tadayuki Takahashi | Summary: We fit the observed high ionisation X-ray absorption lines in the neutron star binary GX13+1 with a full simulation of a thermal-radiative wind. This uses a radiation hydrodynamic code coupled to Monte Carlo radiation transfer […]
Kavli Affiliate: John Silverman | First 5 Authors: Kentaro Nagamine, Ikkoh Shimizu, Katsumi Fujita, Nao Suzuki, Khee-Gan Lee | Summary: In preparation for the IGM tomography study by Subaru Prime Focus Spectrograph (PFS) survey and other large future telescopes such as TMT/ELT/GMT, we present the results of our pilot study on Ly$alpha$ forest and IGM […]
Kavli Affiliate: Chiaki Hikage | First 5 Authors: Chiaki Hikage, Ryuichi Takahashi, Kazuya Koyama, , | Summary: We explore the covariance of redshift-space matter power spectra after a standard density-field reconstruction. We derive perturbative formula of the covariance at the tree-level order and find that the amplitude of the off-diagonal components from the trispectrum decreases […]
Kavli Affiliate: Hiraku Nakajima | First 5 Authors: Alexander Braverman, Michael Finkelberg, Hiraku Nakajima, , | Summary: We deduce the Kazhdan-Lusztig conjecture on the multiplicities of simple modules over a simple complex Lie algebra in Verma modules in category O from the equivariant geometric Satake correspondence and the analysis of torus fixed points in zastava […]

Kavli Affiliate: Andrei Okounkov | First 5 Authors: Andrei Okounkov, , , , | Summary: We revisit the construction of stable envelopes in equivariant elliptic cohomology [arXiv:1604.00423] and give a direct inductive proof of their existence and uniqueness in a rather general situation. We also discuss the specialization of this construction to equivariant K-theory. | […]
Kavli Affiliate: David Spergel | First 5 Authors: Sigurd Naess, Simone Aiola, Jason E. Austermann, Nick Battaglia, James A. Beall | Summary: This paper presents a maximum-likelihood algorithm for combining sky maps with disparate sky coverage, angular resolution and spatially varying anisotropic noise into a single map of the sky. We use this to merge […]
