P. Mormul et F. Pelletier, CONTROLLABILITY BY ABNORMAL CURVES OF 3-D IMENSIONAL DISTRIBUTIONS ONCONNECTED MANIFOLDS OF DIMENSION-5 AND DIMENSION-6, Comptes rendus de l'Academie des sciences. Serie 1, Mathematique, 322(9), 1996, pp. 865-868
The aim of this Note is to prove that for 3-dimensional distributions
on connected manifolds of dimension 5 and 6, having everywhere maximal
growth vector, any two points can be joined by a finite concatenation
of smooth abnormal horizontal curves.
