 +   <hidden TTP97-40  O(\alpha_s^2) Corrections to Top Quark Production at e^+e^- Colliders > In this article we evaluate mass corrections up to $O((m^2/q^2)^6)$ to the 
 + three-loop polarization function induced by an axial-vector 
 + current. Special emphasis is put on the evaluation of the singlet 
 + diagram which is absent in the vector case.  As a physical application 
 + $O(\alpha_s^2)$ corrections to the production of top quarks at 
 + future $e^+e^-$ colliders is considered.  It is demonstrated that for 
 + center of mass energies $\sqrt{s} >~ 500$ GeV the inclusion of the 
 + first seven terms into the cross section leads to a reliable 
 + description.
