# Computing Curvatures

What are some manifolds other than products of space forms for which the various curvature quantities can be computed easily? I'm interested in odd (real) dimensions just as much even, so I'd like to stay away from complex manifolds.

Probably the easiest class of manifolds to compute curvature for are the so called homogeneous spaces, those Riemannian manifolds for which the isometry group acts transitively. Since the isometry group acts transitvely, once one understands curvature at a single point, one understands it everywhere. These examples include (products of) space forms, $\mathbb{C}P^n$ and many other less well known examples.
For, say, simply connected homogeneous manifolds, up through dimension 5 they're all diffeomorphic to the "usual" things - $S^2, S^3, S^4, S^2\times S^2, \mathbb{C}P^2, S^5,$ and $S^2\times S^3$, plus one exceptional example (the Wu manifold). I would start investigating the curvature of homogeneous spaces with the Wu manifold, or with $S^3, S^5,$ or $S^2\times S^3$ with some nonstandard homogeneous metric (the other examples only have standard metrics, if you require the metrics to be homogeneous.)
Is that list of simply connected homogeneous 5-manifolds exhaustive? I'm thinking of $\mathbb{R}^5$ and $\mathbb{H}^5$ in particular. –  Jesse Madnick Jun 25 '11 at 5:51
