Topological modular forms and the absence of all heterotic global anomalies

Posted by klaurent August 30, 2021Tokyo

Kavli Affiliate: Yuji Tachikawa | First 5 Authors: Yuji Tachikawa, Mayuko Yamashita, , , | Summary: We reformulate the question of the absence of global anomalies of heterotic string theory mathematically in terms of a certain natural transformation $mathrm{TMF}^bulletto (I_{mathbb{Z}}Omega^text{string})^{bullet-20}$, from topological modular forms to the Anderson dual of string bordism groups, using the Segal-Stolz-Teichner […]

Concordance: In-flight Calibration of X-ray Telescopes without Absolute References

Posted by klaurent August 30, 2021MIT

Kavli Affiliate: Herman L. Marshall | First 5 Authors: Herman L. Marshall, Yang Chen, Jeremy J. Drake, Matteo Guainazzi, Vinay L. Kashyap | Summary: We describe a process for cross-calibrating the effective areas of X-ray telescopes that observe common targets. The targets are not assumed to be "standard candles" in the classic sense, in that […]

Blázquez-Salcedo-Knoll-Radu Wormholes Are Not Solutions to the Einstein-Dirac-Maxwell Equations

Posted by August 30, 2021Chicago

Kavli Affiliate: Robert M. Wald | First 5 Authors: Daine L. Danielson, Gautam Satishchandran, Robert M. Wald, Robert J. Weinbaum, | Summary: Recently, Bl’azquez-Salcedo, Knoll, and Radu (BSKR) have given a class of static, spherically symmetric, traversable wormhole spacetimes with Dirac and Maxwell fields. The BSKR wormholes are obtained by joining a classical solution to […]

Underwater Acoustic Channel Adaptive Estimation using l21 Norms

Posted by klaurent August 30, 2021Stanford

Kavli Affiliate: Zeeshan Ahmed | First 5 Authors: Amer Aljanabi, Mohanad Abd Shehab, Osama Alluhaibi, Qasim Zeeshan Ahmed, Pavlos Lazaridis | Summary: The problem of underwater acoustic (UWA) channel estimation is the non-uniform sparse representation that may increase the algorithm complexity and the required time. A mathematical framework utilizing l21 constraint with two-dimensional frequency domain […]

Gravitational radiation pulses from Extreme-Mass-Ratio-Inspiral system with a supermassive boson star

Posted by klaurent August 30, 2021Peking

Kavli Affiliate: Pau Amaro Seoane | First 5 Authors: Yu-Peng Zhang, Yan-Bo Zeng, Yong-Qiang Wang, Shao-Wen Wei, Pau Amaro Seoane | Summary: Future space-borne gravitational-wave detectors will observe the gravitational waves in the milli-Hz. Extreme-mass-ratio inspirals with central supermassive black holes are very important sources that could provide the information of the vicinity of black […]
