But in the Lie algebra setting the Killing form is helpful, and the duals of the various finite dimensional representations involved are easy enough to handle. | |
| Mar 7, 2013 at 20:12 | comment | added | Ben McKay | @MTS: yes, dual of the nilradical. But classification of the $P$-invariant subspaces of the nilradical gives those of its dual, and vice versa, so good enough. | |
| Mar 7, 2013 at 16:07 | comment | added | MTS | Isn't $\mathfrak{g}/\mathfrak{p}$ isomorphic to the dual of the nilradical of $\mathfrak{p}$? | |
