Note on bounds for symmetric divergence measures
S. Furuichi, K. Yanagi, K. Kuriyama
I. Sason obtained the tight bounds for symmetric divergence measures are derived by applying the results established by G. L. Gilardoni. In this article, we are going to report two…
Smoothness and monotone decreasingness of the solution to the BCS-Bogoliubov gap equation for superconductivity
Shuji Watanabe, Ken Kuriyama
We show the temperature dependence such as smoothness and monotone decreasingness with respect to the temperature of the solution to the BCS-Bogoliubov gap equation for superconduc…
Lipschitz continuity and monotone decreasingness of the solution to the BCS gap equation for superconductivity
Shuji Watanabe, Ken Kuriyama
In the preceding work \cite{watanabe3}, it is shown that the solution to the BCS gap equation for superconductivity is continuous with respect to both the temperature and the energ…
A generalized Fannes inequality
Shigeru Furuichi, Kenjiro Yanagi, Ken Kuriyama
We axiomatically characterize the Tsallis entropy of a finite quantum system. In addition, we derive a continuity property of Tsallis entropy. This gives a generalization of the Fa…
Trace inequalities for products of matrices
Shigeru Furuichi, Ken Kuriyama, Kenjiro Yanagi
In this short paper, we study some trace inequalities of the products of the matrices and the power of matrices by the use of elementary calculations.
Trace inequalities on a generalized Wigner-Yanase skew information
S. Furuichi, K. Yanagi, K. Kuriyama
We introduce a generalized Wigner-Yanase skew information and then derive the trace inequality related to the uncertainty relation. This inequality is a non-trivial generalization…
