TTP96-11 TOP QUARK PRODUCTION TO ${\cal{O}}(\alpha_s^2)$
The cross-section for the production of $t\bar{t}$ pairs in
$e^+e^-$-annihilation via a virtual photon is determined
up to order $\alpha_s^2$. For the cm-energies of interest the effect
of the top mass may not be considered as a small parameter and the full
mass dependence must be included.
