Abstract:  
In mathematics, we are always interested in understanding when two
objects are essentially the same. For the context of geometric
structures, such as Riemannian and sub-Riemannian manifolds,
"essentially the same" means being connected by an isometry. 

For a Riemannian geometry, the central object measuring the local
obstruction to the existence of an isometry is the curvature tensor of
the Levi-Civita connection. We want to show that similar objects can be
found on sub-Riemannian manifolds with constant nilpotentization, based
on the work of T. Morimoto. 

We will show explicit formulas for a canonical choice of grading and
connection for sub-Riemannian manifolds in some explicit cases.
