On the Resummation of the $\alpha \ln^2 z Terms for QED Corrections to   Deep-Inelastic $ep$ Scattering and $e^+e^-$ Annihilation
  The resummation of the $\alpha \ln^2(z)$ non-singlet contributions is performed for initial state QED corrections. As examples, the effect of the resummation on neutral-current deep-inelastic scattering and the $e^+ e^- \rightarrow \mu^+ \mu^-$ scattering cross section near the $Z^0$-peak is investigated.
