The dimensional reduction of eleven dimensional supergravity into a product of Robertson-Walker spacetime and the seven sphere
The dimensional reduction of eleven dimensional supergravity is discussed. It is shown that there is no dimensional reduction onto Robertson-Walker space with the asymmetric tensorF giving a realistic fluid. Furthermore it is shown that the ansatz’s for the scale factorR:R=atn, R=a exp (btn), andR=aZn, there is no dimensional reduction except the known example of the Freund-Rubin-Englert solution.
