The standard reference for this sort of thing is Stefani, Exact Solutions of Einstein's Field Equations. | |

| Apr 7, 2014 at 9:50 | comment | added | Ben McKay | There is a terminological mismatch between mathematicians and physicists. Mathematicians refer to manifolds with metrics of signature $(-,+,+,+)$ (or $(1,n-1)$) as Lorentzian manifolds, and use the term Riemannian manifold for metric signature $(0,n)$. Many physicists call all signatures Riemannian, apparently. | |
| Apr 7, 2014 at 9:31 | comment | added | Willie Wong | Riemannian manifold with sign signature $(-,+,+,+)$? Are you sure you don't want Lorentzian manifolds and the tag general-relativity? (And in that case, there's a whole book about an open set of examples.) | |
