Query: A singular Darboux type theorem and non-integrable projective
  distributions of degree one   We prove a singular Darboux type theorem for homogeneous polynomial closed
$2$-forms of degree one on $\mathbb{C}^n$. As application, we classify
non-integrable codimension one distributions, of degree one, and arbitrary
classes on projective spaces.
