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…
On 3+1 Dimensional Scalar Field Cosmologies
F. L. Williams, P. G. Kevrekidis, T. Christodoulakis +3
In this communication, we analyze the case of 3+1 dimensional scalar field cosmologies in the presence, as well as in the absence of spatial curvature, in isotropic, as well as in…
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…
