We consider the mixed gravitational Yang-Mills anomaly as the coupling between the K-theory and K-homology of a C \* -algebra crossed product. The index theorem of Connes-Moscovici allows to compute the Chern character of the K-cycle by local formulae involving connections and curvatures. It gives a
