Families of distributions and pfaff systems under duality

A singular distribution on a non-singular variety X can be defined either by a subsheaf D ⊆ TX of the tangent sheaf, or by the zeros of a subsheaf D0 ⊆ Ω1 X of 1-forms, that is, a Pfaff system. Although both definitions are equivalent under mild conditions on D, they give rise, in general, to non-eq...
