Abstract
The logarithmic and constant contributions to the Wilson coefficient of the longitudinal heavy quark structure function to $O(α_s^3)$ are calculated using mass factorization techniques in Mellin space. The small $x$ behaviour of the Wilson coefficient is determined. Numerical illustrations are presented.
