Let G be a Lie group with identity eG and £ a cone in the Lie algebra g of G. We think of g as the set of left invariant vector fields on G and assume furthermore that it satisfies the Lie algebra rank condition. We use a general formalism developed by Sussmann to obtain an algebraic structure on the covering space “(£,x), xG, recently presented by Colonius-Kizil-San Martin. This formalism provides a Lie group of exponentials of Lie series and a subsemigroup S that parametrizes the space of controls by means of Chen series. The main purpose of the project is to obtain the monotonic covering “(£,x) as appropriate quotients of the above semigroup S through congruence relations on semigroups. (AU)
