| Oct 29, 2009 at 8:49 | comment | added | Urs Schreiber | I doubt that the notion of cohomology as being the connected components in a hom-space of an (oo,1)-topos or stable (oo,1)-category is not expansive enough. I haven't looked into equivariant constructions with the orbit category, though. Would be interesting to figure out how to say that more generally. | |
| Oct 29, 2009 at 3:50 | comment | added | Mike Shulman | That's a shame, because for some purposes the more interesting type of equivariant cohomology is Bredon cohomology, which is naturally RO(G)-graded and Mackey-functor-valued. Perhaps a more expansive notion of cohomology is in order? | |
