Abstract: We develop a general procedure, based on the renormalized eta-cochain, whichallows to find local representatives of the bivariant Chern character offinitely summable quasihomomorphisms. In particular, using zeta-functionrenormalization we obtain a bivariant generalization of the Connes-Moscoviciresidue formula, and explain the link with chiral and multiplicative anomaliesin quantum field theory.
