The automorphism groupof the free groupacts on a spaceof Jacobi diagrams of degree d on n oriented arcs. We study the-module structure ofby using two actions on the associated graded vector space of: an action of the general linear groupand an action of the graded Lie algebraof the IA-automorphism groupofassociated with its lower central series. We extend the action ofto an action of the associated graded Lie algebra of the Andreadakis filtration of the endomorphism monoid of. By using this action, we study the-module structure of. We obtain an indecomposable decomposition ofas-modules for. Moreover, we obtain the radical filtration offorand the socle of.
