Nov 20, 2012 at 18:50 | comment | added | Tatin | Yes. A vector subspace. | |
Nov 20, 2012 at 18:47 | comment | added | algori | tatin -- when you say "Let $N$ be a subspace" do you mean a vector subspace? | |
Nov 20, 2012 at 18:29 | comment | added | Tatin | Note that, your example is not the right one. For $\omega_{+}$,$\omega_{-}$ both cannot be in $N$ as $\omega_{+}+\omega_{-}=2dx_1\wedge dy_1$ which is decomposable whereas $N$ cannot contain non-zero decomposable forms. | |
Nov 20, 2012 at 17:56 | comment | added | algori | This seems to be false for $n=4$: take $\omega_{\pm}=dx_1\wedge dy_1\pm dx_2\wedge dy_2$; then $\omega_+\wedge\omega_+=-\omega_-\wedge\omega_-$. | |
