The isotropy of compact universes
2001
Classical and quantum gravity
We discuss the problem of the stability of the isotropy of the universe in the space of ever-expanding spatially homogeneous universes with a compact spatial topology. The anisotropic modes which prevent isotropy being asymptotically stable in Bianchi-type VII_h universes with non-compact topologies are excluded by topological compactness. Bianchi type V and type VII_h universes with compact topologies must be exactly isotropic. In the flat case we calculate the dynamical degrees of freedom of
