Elementary divisors of Cartan matrices for symmetric groups
Katsuhiro Uno, Hiro-Fumi Yamada
The purpose of this paper is to give a simple expression of the elementary divisors of the cartan matrices for the symmetric groups.
Eclipsing Light-Curve Asymmetry for Black-Hole Accretion Flows
Ken-ya Watarai, Rohta Takahashi, Jun Fukue
We propose an eclipsing light-curve diagnosis for black-hole accretion flows. When emission from an inner accretion disk around a black hole is occulted by a companion star, the ob…
Multiwavelength Observations of 3C 66A during the WEBT campaign of 2003 - 2004
M. Boettcher, J. Harvey, M. Joshi
The BL Lac object 3C 66A was the target of an extensive multiwavelength monitoring campaign from July 2003 through April 2004, involving observations throughout the electromagnetic…
Geometrical Effect of Supercritical Accretion Flows: Observational Implications of Galactic Black-Hole Candidates and Ultraluminous X-ray Sources
K. Watarai, K. Ohsuga, R. Takahashi +1
We investigate the dependence of the viewing angle in supercritical accretion flows and discuss the observational implications of galactic black-hole candidates and ultraluminous X…
Spectroscopic Studies of Very Metal-Poor Stars with the Subaru High Dispersion Spectrograph. III. Light Neutron-Capture Elements
Wako Aoki, Satoshi Honda, Timothy C. Beers +7
Elemental abundance measurements have been obtained for a sample of 18 very metal-poor stars using spectra obtained with the Subaru Telescope High Dispersion Spectrograph. Seventee…
Concavity of the auxiliary function appearing in quantum reliability function an classical-quantum channels
Jun Ichi Fujii, Ritsuo Nakamoto, Kenjiro Yanagi
Concavity of the auxiliary function which appears in the random coding exponent as the lower bound of the quantum reliability function for general quantum states is proven for s be…
