Abstract
Recently Tomonaga and Schwinger have independently developed a covariant formulation of quantumelectrodynamics (super-many-time theory), and have successfully applied it to the explanation of the Lamb shift in the hydrogen atom and the anomalous magnetic moment of the electron. They have shown that, although the present theory of fields, in general, gives infinte answers to such field reaction problems, since it cannot be formulated in a Lorentz- and gauge-covariant way without introduction of the singular delta function of Jordan and Pauli, it is nevertheless possible to avaid the divergences by amalgamating them into the mass and charge, and that the remaining finite term can well account for the experimental facts. But there remains the question, whether or not such finite term, as is separated from infinity, can be free from any ambiguity arising from the pathological character of delta function of Jordan and Pauli.
