Equivalence for Differential Equations
Odinette Renée Abib
We shall study the equivalence problem for ordinary differential equations with respect to the affine transformations group.

Differential equations and moving frames
Odinette Renée Abib
The purpose of the paper is to study the relationship between differential equations, Pfaffian systems and geometric structures, via the method of moving frames of E.Cartan. We sho…

Geodesics in nilpotent Lie groups
Odinette Renée Abib
We study the geodesics problem in Heisenberg group H (case SR and riemannian). The sheaf of infinitesimal automorphisms of the (2n,2n+1) distribution D over H is an infinite, trans…
