Quantum cosmology of Bianchi VIII, IX LRS geometries
A. Karagiorgos, T. Pailas, N. Dimakis +3
In the present work we revisit the axisymmetric Bianchi VIII and IX models. At the classical level we reproduce the known analytic solution, in a novel way making use of two quadra…
Reduced Lagrangians and analytic solutions in Einstein-æther Cosmology
M. Roumeliotis, A. Paliathanasis, Petros A. Terzis +1
We present the solution space of the field equations in the Einstein-æther theory for the case of a and a LRS Bianchi Type space-time. We also find that there are port…
Integrability of the mixmaster model
N. Dimakis, Petros A. Terzis, T. Christodoulakis
The mixmaster model has always been a field of controversy in the literature regarding its (non)integrability. In this work, we make use of a generalized definition of a class of n…
The solution space to the Einstein's vacuum field equations for the case of five-dimensional Bianchi Type I (Type 4A1)
T. Pailas, Petros A. Terzis, T. Christodoulakis
We consider the 4+1 Einstein's field equations (EFE's) in vacuum, simplified by the assumption that there is a four-dimensional sub-manifold on which an isometry group of dimension…
