Links Helffer-Nourrigat cone of singular foliations to Nash algebroids and characterizes longitudinally elliptic operators via symplectic leaves of holonomy Lie algebroids.
Constructs a series of Nash blowups of singular foliations that turn any such foliation into a Debord foliation after one step, recovering prior cases for i=0 and i=1.
