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 ...
