| May 14, 2019 at 18:30 | comment | added | user20948 | I get stuck with this computation, especially about the sign convention. Given this diagonal approximation, do we succeed to find a commutative differential graded algebra representing $\mathbb Z^{hG}\simeq\operatorname{RHom}_{\mathbb ZG}(\mathbb Z,\mathbb Z)$? | |
| Jun 18, 2013 at 23:56 | comment | added | Ricardo Andrade | Since the question asked for a reference, I will say that Chris Gerig's calculation esssentially appears with some more elaborations in section 7 of chapter XII (pages 250-252) of the book "Homological algebra" by Cartan and Eilenberg. There the calculation is phrased in terms of Tate cohomology, which agrees with group cohomology in positive degrees (including the ring structure). | |
