On the essential constants in Riemannian geometries
G. O. Papadopoulos
In the present work the problem of distinguishing between essential and spurious (i.e., absorbable) constants contained in a metric tensor field in a Riemannian geometry is conside…

Space Time Covariance of Canonical Quantization of Gravity: A (formal) general result and the (rigorous) explicit case of 2+1 Quantum Cosmology
T. Christodoulakis, G. O. Papadopoulos
A general classical theorem is presented according to which all invariant relations among the space time metric scalars, when turned into functions on the Phase Space of full Pure…

On 3+1 Dimensional Friedman-Robertson-Walker Universes with Matter
T. Christodoulakis, C. Helias, P. G. Kevrekidis +2
We examine the dynamical behavior of matter coupled to gravity in the context of a linear Klein-Gordon equation coupled to a Friedman-Robertson-Walker metric. The resulting ordinar…
