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 $\omega_+\wedge\omega_+=-\omega_-\wedge\omega_-$.
