Abstract
In this talk I shall review the role of the light-cone zero modes in accommodating such features as degenerate vacua, condensates and anomalies in the light-cone representation. In addition to discussing the mechanisms by which the zero modes represent these features, I shall discuss the (still not completely solved) problem of calculating the dynamical operators in the presence of these zero modes. I shall illustrate my remarks, first with the best studied case — the Schwinger model — then with QED in 3+1 dimensions and QCD in 1+1 dimensions. I shall also remark on the possible relation of my remarks to an inconsistency in published solutions to the ’t Hooft model.
