Query: New Approach to Quantization of Cosmological Models   We propose the new quantization of homogenous cosmological models. Four
fundamental methods are applied to the cosmological model and efficiently
jointed. The Dirac method for constrained systems is used, then the Fock space
is built and the 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
quantum cosmological model is introduced.
