23. A. Borel, Ann. Math., Vol. 72 (Princeton University Press, 1960). Borel's denseness theorem states that if a compact space M is topologically M̃/Γ with a manifold M̃ admitting a homogeneous metric invariant under a transformation group G isomorphic to a product of noncompact simple groups and its discrete subgroup Γ, the lift g̃ to M̃ of any metric g on M is G-invariant if g̃ is invariant under one-dimensional Lie subgroup of G.
24. G. D. Mostow, Ann. Math. Stud., Vol. 78 (Princeton University Press, 1973). Mostow showed that if the centre of G is a finite group and G does not have a factor isomorphic to SL(2,ℝ), there exists no moduli freedom in the choice of Γ.
25. Unfortunately, their physical implications to higher-dimensional cosmology are not certain at present because the most favourable compactifications in the string theory utilize Calabi-Yau manifolds, which generally admit the moduli freedom of the complex and the Kähler structures, to respect supersymmetry. However, since supersymmetry must be broken and harmful moduli fields should be eliminated in a final theory, there is a possibility that the rigidity theorem in higher dimensions may play a significant role in finding the final theory.
