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
The running coupling constant can be estimated by computing gluon two-and three-point Green functions from the lattice. Computing in lattice implies working in a fixed gauge sector (Landau). A source of systematic uncertainty is then the contribution of non gauge-invariant condensates, as (A2), gene
