Sep 4, 2012 at 1:11 | comment | added | Peter May | I just saw the comment about Bredon. He introduced ordinary $\mathbf{Z}$-graded cohomology theories, in 1966 I believe. (I heard him talk about it that year). Most people outside core algebraic topology mean Borel cohomology, not Bredon cohomology, when they say "equivariant cohomology'', and Borel certainly came earlier. Of course, neither considered $RO(G)$-grading. | |
