Abstract
The O(..cap alpha../sub s/) perturbative quantum-chromodynamic corrections to weak, charged-current production of heavy quarks are evaluated. For perturbative subtractions and parton densities defined via the electroproduction structure function F*/sub 2/, the residual corrections to ..nu..N flavor-production structure functions are shown to be modest except for x'..-->..1 or Q/sup 2/ ..cc-bar splitting ''singularities'' into evolution of an intrinsic charm-sea component of the nucleon. The longitudinal structure function due to charm production is computed and found to be substantial.
