Hadronic Currents. II

In a series of earlier papers, a theory of self-induced strong interactions was proposed by Frye and Susskind. The matrix elements of additive currents were conjectured to satisfy certain simple "$X$ representations." We show that a class of quantities called "limit projections" defined at infinite momentum have certain properties which can be proved in perturbation theory. These properties imply immediately the $X$ representations conjectured for currents. Further, these limit projections are shown to be closely related to matrix elements of currents at infinite momentum.
