The small growth invariants of Goursat distributions
Susan Jane Colley, Gary Kennedy, Corey Shanbrom
This is the second of a pair of papers devoted to the local invariants of Goursat distributions. The study of these distributions naturally leads to a tower of spaces over an arbit…

The structural invariants of Goursat distributions
Susan Jane Colley, Gary Kennedy, Corey Shanbrom
This is the first of a pair of papers devoted to the local invariants of Goursat distributions. The study of these distributions naturally leads to a tower of spaces over an arbitr…

Detecting flat normal cones using Segre classes
S. J. Colley, G. Kennedy
Given a flat, projective morphism from an equidimensional scheme to a nonsingular curve and a subscheme of , we give conditions under which specialization of the S…
