The Hamiltonian approach to General Relativity and CMB primordial spectrum
B. M. Barbashov, V. N. Pervushin, A. F. Zakharov +1
Approaches to solutions of problems of the energy, time, Hamiltonian operator quantization of the General Relativity, the creation of the Universe from vacuum are considered in the…
Bogoliubov's Integrals of Motion in Quantum Cosmology and Gravity
V. N. Pervushin, V. A. Zinchuk
Quantum Cosmology and Gravity are formulated here as the primary and secondary quantizations of the energy constraints by analogy with the historical formulation of quantum field t…
Hamiltonian General Relativity in Finite Space and Cosmological Potential Perturbations
B. M. Barbashov, V. N. Pervushin, A. F. Zakharov +1
The Hamiltonian formulation of general relativity (GR) is considered in finite space-time and a specific frame of reference given by the diffeo-invariant components of the Fock sim…
Quantum Gravity as Theory of "Superfluidity"
B. M. Barbashov, V. N. Pervushin, A. F. Zakharov +1
A version of the cosmological perturbation theory in general relativity (GR) is developed, where the cosmological scale factor is identified with spatial averaging of the metric de…
CMBR anisotropy: theoretical approaches
B. M. Barbashov, V. N. Pervushin, A. F. Zakharov +1
The version of the cosmological perturbation theory based on exact resolution of energy constraint is developed in accordance with the diffeomorphisms of general relativity in the…
Quantum Cosmological Origin of Universes
V. N. Pervushin, V. A. Zinchuk
A direct pathway from Hilbert's ``Foundation of Physics'' to Quantum Gravity is established through Dirac's Hamiltonian reduction of General Relativity and Bogoliubov's transformat…
