,Geometry of Hörmander’s Vector Fields,induced by a system of vector fields, which are contained in some papers of the middle 1980’s. This area is by a now an independent field of study, but here we are mainly interested in its relevance in connection with the study of second order PDEs of Hörmander’s type.
