Decoupling of the general scalar field mode and the solution space for Bianchi type I and V cosmologies coupled to perfect fluid sources
T. Christodoulakis, Th. Grammenos, Ch. Helias +2
The scalar field degree of freedom in Einstein's plus Matter field equations is decoupled for Bianchi type I and V general cosmological models. The source, apart from the minimally…
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…
