Bogolyubov’s integrals of motion in quantum cosmology and gravity

Quantum cosmology and gravity are defined here as the primary and secondary quantizations of the energy constraints by analogy with the historical formulation of quantum field theory given in the 20th century. A new fact is that both the Universe and its matter are created from stable vacuum obtained by the Bogolyubov transformations applied to description of quantum superfluid liquid. We show that the quantum gravity makes it possible to explain topical problems of cosmology by the cosmological creation of both universes and particles from Bogolyubov’s vacuum.
