QUANTUM-FIELD THEORY OF THE UNIVERSE IN THE KANTOWSKI-SACHS SPACE-TIME

In this paper, the quantum field theory of the Universe in the Kantows ki-Sachs space-time is studied. We apply an analogue of proceeding in quantum field theory in curved spate-time to the Kantowski-Sachs space -time, and obtain the wave function of the Universe satisfied the Whee ler-De Witt equation. Regarding the wave function as a universe field in the minisuperspace, we can not only overcome the difficulty of the probabilistic interpretation in quantum cosmology, but also come to th e conclusion that there is multiple production of universes. The avera ge number of the produced universes from nothing is calculated. The di stribution of created universes is given. We find that it is the Planc kian distribution.
