Query: Degeneracy loci of twisted differential forms and linear line complexes   We prove that the Hilbert scheme of degeneracy loci of pairs of global
sections of Omega(2), the twisted cotangent bundle on P^(n-1), is unirational
and dominated by the Grassmannian of lines in the projective space of
skew-symmetric forms over a vector space of dimension n. We provide a
constructive method to find the fibers of the dominant map. In classical
terminology, this amounts to giving a method to realize all the pencils of
linear line complexes having a prescribed set of centers. In particular, we
show that the previous map is birational when n=4.
