Conditional Symmetries and the Canonical Quantization of Constrained Minisuperspace Actions: the Schwarzschild case
T. Christodoulakis, N. Dimakis, Petros A. Terzis +4
A conditional symmetry is defined, in the phase-space of a quadratic in velocities constrained action, as a simultaneous conformal symmetry of the supermetric and the superpotentia…

Numerical space-times near space-like and null infinity. The spin-2 system on Minkowski space
Florian Beyer, Georgios Doulis, Jörg Frauendiener +1
In this paper we demonstrate for the first time that it is possible to solve numerically the Cauchy problem for the linearisation of the general conformal field equations near spac…
