| Feb 23, 2016 at 12:12 | comment | added | Fernando Muro | @SebastianGoette You're right, I somehow missed the track of the fact that we have a tensor product. | |
| Feb 23, 2016 at 12:09 | comment | added | Sebastian Goette | @FernandoMuro I don't understand your comment (or maybe I don't understand the question correctly). $G=\{1\}$ gives the algebraic Künneth formula at $E_2$, which holds without Tor terms because $\mathbb C$ is a field. Note however that the tensor product of singular cochain complexes is not the singular cochain complex of the product, so the example at the end is misleading. | |
| Feb 23, 2016 at 11:36 | comment | added | Fernando Muro | The answer is not positive in general, not even for $G$ finite. Take $G=\{1\}$. You can also construct more involved examples, of course. | |

Corrected Borel construction near the very end.

| Nov 23, 2014 at 21:34 | comment | added | Yeping Zhang | It is tensor product over $\mathbb{C}$, and yes, i wrote $\oplus$ by mistake, thanks a lot. | |

| Nov 23, 2014 at 21:31 | comment | added | John Pardon | Is this tensor product over $\mathbb C$ or over $\mathbb C[G]$? (I assume you must mean $\otimes$ instead of $\oplus$ in the definition of the product complex). | |
