Abstract:
Let Γ be a Lie group.Then any automorphism of the free group of rank n induces a diffeomorphism of Γn. We use this remark and a result of P. Vogel to construct linear representations of a certain automorphism group of the algebraic closure of the free group. This automorphism group is closely related to the string link cobordism group.
