On Schrödinger equations in Einstein's theory of gravity
1998This paper deals with the Hamiltonian formalism and consecutive canonical quantization of a system composed by incoherent matter coupled with its own gravitational field. The system is studied within the framework of general relativity. Incoherent matter is described by giving a line congruence and assuming that the energy of the matter satisfies a ...
