Fragmentation Function Method for Charge Asymmetry Measurements in   $\e^+e^-$ Collisions
  We propose a method for measuring the hadron charge asymmetry in $\ee$ collisions which is based upon the fragmentation function formalism, and is largely independent of modelling of fragmentation effects. Furthermore, in this method, QCD radiative corrections can be accounted for in a systematic way.
