Twisted first homology groups of the automorphism group of a free group

The automorphism group AutFn and outer automorphism group OutFn of a free group FnFn of rank n act on the abelianized group H   of FnFn and the dual group H*H* of H  . The twisted first homology groups of AutFn and OutFn with coefficients in H   and H*H* are calculated.
