Query: Hadronic corrections to muon anomalous magnetic moment within the
  instanton liquid model   The current status of the muon anomalous magnetic moment problem is briefly
presented. The corrections to muon anomaly coming from the effects of hadronic
vacuum polarization, Z*\gamma\gamma* effective vertex and light-by-light
scattering are estimated within the instanton model of QCD vacuum.
