A complete description of dynamics of compact locally homogeneous univ
erses is given, which, in particular, includes explicit calculations o
f Teichmuller deformations and careful counting of dynamical degrees o
f freedom, We regard each of the universes as a simply connected four-
dimensional space-time with identifications by the action of a discret
e subgroup of the isometry group. We then reduce the identifications d
efined by the space-time isometries to ones in a homogeneous section,
and find a condition that such spatial identifications must satisfy. T
his is essential for explicit construction of compact homogeneous univ
erses. Some examples are demonstrated for Bianchi II, VI0, VII0, and I
universal covers. (C) 1997 American Institute of Physics.
