Stability of self-consistent higher-dimensional cosmological solutions
Abstract
The problem of self-consistent solutions in higher-dimensional spacetimes is considered. The importance of quantum effects in this analysis is emphasized. It is shown how the one-loop effective action for conformally invariant matter fields on a time-dependent Kaluza-Klein background may be obtained from previously known results on static backgrounds. The field equations are obtained and solved for self-consistent solutions in cases for which the four-dimensional part of the space is a Friedmann-Robertson-Walker space. Stability of the solutions to small perturbations is studied. All solutions, including the product of flat four-dimensional space with a sphere, are shown to be unstable.
