Abstract
model of gravitation in the frameworks of the Hamiltonian (Dirac) approach is considered.
The equations, setting dependence of observable density of number of scalar particles on the
initial data and invariant parametre of evolution, are constructed in an explicit form.
Problems of unification of principles of the General Theory of Relativity (GTR) and the
Quantum Theory of Fields (QTF) within a simple example of a vacuum creation of scalar
particles in conformal-invariant model of gravitation [1-3,10-14] are considered. It is shown
that such model can describe both possible mechanism of such creation, and ways of its
generalisation to more complex models, including Standard Model (SM).
It allows to formulate some new approach to quantization of the relativistic gravitational
systems, which essence is in quantization of the phase space of initial quantities as integrals
of motion of the system, obtained by Bogoljubov diagonalization of the motion equations in
Hamiltonian formalism, and in the proof of equivalence of such quantization to transition
from classical commutative variables to their noncommutative quantum analogues.
The above described scheme can be applied to initial manifolds of any finite dimension and
topology.
