Role of the remnant symmetries in gravitational theories based on absolute parallelism: a 2D standpoint
Franco Fiorini, Andronikos Paliathanasis
By using simplified 2D gravitational, non-local Lorentz invariant actions constructed upon the torsion tensor, we discuss the physical meaning of the remnant symmetries associated…
Dynamical analysis and cosmological evolution in Weyl integrable gravity
Andronikos Paliathanasis
We investigate the cosmological evolution for the physical parameters in Weyl integrable gravity in a Friedmann--Lema\^ıtre--Robertson--Walker universe with zero spatially curvatur…
Anisotropic Spacetimes in Chiral Scalar Field Cosmology
A. Giacomini, P. G. L. Leach, G. Leon +1
Study the behaviour and the evolution of the cosmological field equations in an homogeneous and anisotropic spacetime with two scalar fields coupled in the kinetic term. Specifical…
An extended analysis for a generalized Chaplygin gas model
Abdulla Al Mamon, Andronikos Paliathanasis, Subhajit Saha
In this work, we have extended the analysis on the generalized Chaplygin gas (GCG) model as the unification of dark energy and dark matter. Specifically, we have shown that the mod…
Quantum Cosmology in theory
N. Dimakis, A. Paliathanasis, T. Christodoulakis
We use Dirac's method for the quantization of constrained systems in order to quantize a spatially flat Friedmann-Lemaître-Robertson-Walker spacetime in the context of cosmo…
Global dynamics and evolution for the Szekeres system with nonzero cosmological constant term
Andronikos Paliathanasis, Genly Leon
The Szekeres system with cosmological constant term describes the evolution of the kinematic quantities for Einstein field equations in . In this study, we investigat…
