| Dec 4, 2017 at 13:54 | comment | added | Denis Nardin | I said, Borel cohomology, which is just the cohomology of the homotopy orbits (yes, that is also $RO(G)$-graded) | |
| Dec 4, 2017 at 13:41 | comment | added | Steve Costenoble | Related, but actually rather different. $RO(\mathbb Z/2) \cong \mathbb Z \times \mathbb Z$ and the $RO(\mathbb Z/2)$-graded cohomology of a point is quite a bit more complicated than this calculation. | |

| Dec 4, 2017 at 8:22 | comment | added | Denis Nardin | This looks like the $RO(G)$-grading on the Borel cohomology of the point | |
