Abstract
For the structure functions of the quark propagator, the asymptotic be havior is obtained for general, linear, covariant gauges, and in all d irections of the complex k(2)-plane. Asymptotic freedom is assumed. Co rresponding previous results for the gauge field propagator are import ant in the derivation. Except for coefficients, the leading asymptotic terms are determined by one-loop or by two-loop information, and are gauge independent. Various sum rules are derived.
