A new approach to quantization of cosmological models

We propose new quantization of homogenous cosmological models. Four fundamental methods are applied to the cosmological model and efficiently joint. The Dirac method for constrained systems is used, then the Fock space is built, and second quantization is carried out. Finally, the diagonalization ansatz, which is a combination of the Bogoliubov transformation method and the Heisenberg equation of motion, is formulated. The temperature of a quantum cosmological model is introduced.
