| Feb 15, 2020 at 22:28 | comment | added | Loring Tu | This is a response to Selena Auckland's edit of August 5 '19. When a k-form and an (n-k)-form are exchanged in a wedge product, the resulting sign is $(-1)^{k(n-k)}$, not $(-1)^k (-1)^{n-k}$. Otherwise, I think your edit is correct. | |

| Aug 5, 2019 at 5:37 | comment | added | Selene Auckland | Thanks! Oh wait I think I get it now, Prof Tu. Do you mean $[\eta_S] := (-1)^{k} (-1)^{n-k} [\gamma_S] := [(-1)^{k} (-1)^{n-k} \gamma_S]$? Please see my edit to my question. | |
