Information Entropy in Cosmology
Akio Hosoya, Thomas Buchert, Masaaki Morita
The effective evolution of an inhomogeneous cosmological model may be described in terms of spatially averaged variables. We point out that in this context, quite naturally, a meas…

Hamiltonians for Compact Homogeneous Universes
Masayuki Tanimoto, Tatsuhiko Koike, Akio Hosoya
We briefly show how we can obtain Hamiltonians for spatially compact locally homogeneous vacuum spacetimes. The dynamical variables are categorized into the curvature parameters an…
Black Hole Singularity and Generalized Quantum Affine Parameter
Akio Hosoya, Ichiro Oda
We study a behavior of quantum generalized affine parameter (QGAP), which has been recently proposed by one of the present authors, near the singularity and the event horizon in th…
