Quantization of Einstein-aether Scalar field Cosmology
N. Dimakis, T. Pailas, A. Paliathanasis +3
We present, for the first time, the quantization process for the Einstein-aether scalar field cosmology. We consider a cosmological theory proposed as a Lorentz violating inflation…
"Time"-covariant Schrödinger equation and the canonical quantization of the Reissner-Nordström black hole
T. Pailas
A "time"-covariant Schrödinger equation is defined for the minisuperspace model of the Reissner-Nordström (RN) black hole, as a "hybrid" between the "intrinsic time" Schrödinger an…
Infinite dimensional symmetry groups of the Friedmann equations
T. Pailas, N. Dimakis, Andronikos Paliathanasis +2
We find the symmetry generators for the Friedman equations emanating from a perfect fluid source, in the presence of a cosmological constant term. The relevant dynamics is seen to…
On solvable Lie algebras and integration method of ordinary differential equations
T. Pailas, P. A. Terzis, T. Christodoulakis
Some more general "inheritance conditions" have been found for a given set of symmetry generators acting on some set of coupled ordinary differential equ…
