Titolo: THE GEOMETRIC FORMULATION OF QUANTUM STATISTICS AND MEASURES OF QUANTUM INFORMATION
Abstract: The notion of "metric adjusted skew information" provides a link between quantum information theory and the theory of measures of quantum information initiated by Wigner, Yanase and Dyson. The relationship is made tangible by several classification theorems for special classes of operator monotone functions, and they provide us with explicit formulae for the common used measures of quantum information. As an application it is shown that the newly introduced Chen-Luo skew information is convex.
