Abstract
Complete two-loop electroweak corrections to leptonic anomalous magnet ic moments have been calculated recently using asymptotic expansions o f Feynman diagrams. Techniques developed in that context can also be a pplied to the electric dipole moments (EDM) of fermions. In the Standa rd Model the EDM was proved to vanish at two loops. In this talk we di scuss a simplification of that proof.
