Mar 4, 2012 at 15:08 | comment | added | darij grinberg | Yes. It is the linear independence that I don't understand. | |
Mar 4, 2012 at 12:33 | comment | added | Theo Johnson-Freyd | So that I understand the question, the point is that $\Omega_p$ is an odd-degree form if $p$ is odd (and already $0$ if $p$ is even), and so there cannot be any terms of form $\Omega_p \wedge \Omega_p = -\Omega_p \wedge\Omega_p$. So it follows that your sequences are a spanning set, and the only thing missing is the independence? Put another way, the question is why the ring of invariants is a polynomial algebra (on odd variables) and not a quotient thereof? | |
