Canonical quantization of some midi-superspace models in 2+1 and 3+1 dimensions
Christodoulakis, T.; Doulis, G.; Terzis, P. A.; Melas, E.; Grammenos, Th; Papadopoulos, G. O.; Spanou, A. (2009)A proposal is put forward which enables the canonical quantization of a family of axially symmetric geometries in 2+1 dimensions and a corresponding spherically symmetric family in 3+1 dimensions. The proposal consists of ... -
Locally homogeneous spaces, induced Killing vector fields and applications to Bianchi prototypes
Papadopoulos, G. O.; Grammenos, T. (2012)An answer to the question: Can, in general, the adoption of a given symmetry induce a further symmetry, which might be hidden at a first level? has been attempted in the context of differential geometry of locally homogeneous ... -
Towards canonical quantum gravity for 3+1 geometries admitting maximally symmetric two-dimensional surfaces
Christodoulakis, T.; Doulis, G.; Terzis, P. A.; Melas, E.; Grammenos, T.; Papadopoulos, G. O.; Spanou, A. (2010)The canonical decomposition of all 3+1 geometries admitting two-dimensional space-like surfaces is exhibited as a generalization of a previous work. A proposal, consisting of a specific renormalization Assumption and an ... -
Towards canonical quantum gravity for G(1) geometries in 2+1 dimensions with Lambda-term
Christodoulakis, T.; Doulis, G.; Terzis, P. A.; Melas, E.; Grammenos, T.; Papadopoulos, G. O.; Spanou, A. (2008)The canonical analysis and subsequent quantization of the (2+1)-dimensional action of pure gravity plus a cosmological constant term is considered, under the assumption of the existence of one spacelike Killing vector ...
