Tóm tắt

It is urged that the lesson of gauge invariance in quantum electrodynamics implies the irrelevance of «Schwinger term» difficulties in current algebra. The divergence equations of Veltman form the basis of a gauge-variation formalism in which these questions are avoided. Утверждается, что урок калибровочной инвариантности в квантовой злектродинамике указывает на то, что в алгебре токов трудности «выражения Швингера» не имеют отношения к делу. Расходящиеся уравнения Вельтмана образуют основу для калибровочно-вариационного формализма, в котором удается обойти эти вопросы.
