摘要
Using canonical forms on S-7, viewed as an SU(2) bundle over S-4, we introduce consistent ansatze for the 4-form field strength of 11-dimensional supergravity and rederive the known squashed, stretched and the Englert solutions. Furthermore, by rewriting the metric of S7 as a U(1) bundle over CP3, we present yet more general ansatze. As a result, we find a new compactifying solution of the type AdS(5) x CP3, where CP3 is stretched along its S-2 fiber. We also find a new solution of AdS(2) x H-2 x S-7 type in Euclidean space.
