Query: Computing Techniques for Two-Loop Corrections to Anomalous Magnetic
  Moments of Leptons   Two-loop electroweak corrections to the electron, muon, and tau lepton
anomalous magnetic moments have been computed recently. Effects of hadronic
contributions to the photon propagator in two-loop QED corrections have also
been reanalysed. The common technique used in both calculations was asymptotic
expansion of Feynman diagrams in the ratio of lepton mass to some heavy mass
scale. In this talk we present some details of this method paying particular
attention to the expansion of multi-scale diagrams.
