摘要
Given a canonical basis of C-1-smooth vector fields {(X) over tilde (i)} satisfying certain restrictions on commutators, we prove an existence theorem for their local nilpotent homogeneous approximation at the origin using the methods of the group analysis of differential equations. We study the properties of the quasimetrics induced by some systems of vector fields related to {(X) over tilde (i)}.
