Query: The Bianchi Type I minisuperspace model   The minisuperspace model of a Bianchi Type I universe with compact spatial
sections is investigated. The classical solutions are brought onto a form were
the difference between compact and infinite spatial sections are manifest. One
of the features of the compact case is that it has a non-trivial moduli space.
The solution space of the compact Bianchi Type I universe is 10 dimensional
whereas the Kasner solutions only have a 1 dimensional solution space. We also
include the classical solutions with dust and a cosmological constant.
Solutions to the Wheeler-DeWitt equation are obtained in light of the tunneling
boundary proposal by Vilenkin. Backreaction effects from a simple scalar field
are also investigated.
