dc.descriptionWe describe the calculation of the two--loop massive operator matrix elements for massive external fermions. These matrix elements are needed for the calculation of the $O(α^2)$ initial state radiative corrections to $e^+e^-$ annihilation into a neutral virtual gauge boson, based on the renormalization group technique.
