| Feb 14, 2011 at 22:32 | comment | added | José Figueroa-O'Farrill | Indeed, it's §26 in the Chevalley--Eilenberg paper: ams.org/mathscinet-getitem?mr=24908 | |
| Feb 14, 2011 at 21:03 | comment | added | José Figueroa-O'Farrill | Any treatment of Lie algebra cohomology should do it. I think it even goes back to the original paper of Chevalley--Eilenberg, but I'n not sure. | |
| Feb 14, 2011 at 21:00 | comment | added | Pietro Tortella | Yes, it should be a cocycle, forgot to tell it. Where can I find about central extensions? | |

| Feb 14, 2011 at 20:45 | comment | added | José Figueroa-O'Farrill | I take it that $Q$ is a cocycle? If so, then what you are defining is a quotient of the universal enveloping algebra of the central extension of $\mathfrak{g}$. | |
