Abstract
Spin-dependent quark and gluon distribution functions are derived in terms of light-cone correlation functions. The first moment of the gluon asymmetry Δg is shown to be related to the Chern-Simons current . Renormalization and factorization ambiguities and their implication for the problem are discussed.
