The Hamiltonian constraint and its possible deformations |
|
Abstract |
The role of the Hamiltonian constraint is discussed within GR, its possible modifications within the Dirac hypersurface-deformation algebra and its consequences for the corresponding Poincar\'e algebra are investigated for quantum-gravity models. Possible corresponding non-commutative spaces are analyzed with their Heisenberg algebra. The semiclassical transition is found relevant for the definition of asymptotically-flat classical spaces originated from quantum spaces whose symmetry group is more general than that exhibited by the (quantized) Schwarzschild solution. |
