Query: Integral Relations for Twist 2 abd Twist 3 Contributions to Polarized
  Structure Functions   We discuss the relations between the twist 2 and twist 3 contributions to
polarized deep-inelastic scattering structure functions both for neutral and
charged current interactions which are predicted by the operator product
expansion in lowest order in QCD.
