Accelerating cosmologies from compactification

Description
A solution of the (4+n)-dimensional vacuum Einstein equations is found for which spacetime is compactified on an n-dimensional compact hyperbolic manifold (n≥2) of time-varying volume to a flat four-dimensional Friedmann-Lemaitre-Robertson-Walker cosmology undergoing a period of accelerated expansion in the Einstein conformal frame. This shows that the 'no-go' theorem forbidding acceleration in 'standard' (time-independent) compactifications of string or M theory does not apply to 'cosmological' (time-dependent) hyperbolic compactifications
