The Tomonaga–Schwinger equation in flat space-time

John Frencha)

P.O. Box 514, Perry, Maine 04667, USA


A derivation of the Tomonaga–Schwinger equation is presented based on defining a wave functional on a general spacelike surface such that the expectation values match those in the corresponding Heisenberg picture. This derivation is carried out in flat space-time.


Une dérivation de l’équation de Tomonaga-Schwinger est présentée sur la base de la définition d’une fonction d’onde sur une surface générale semblable à un espace telle que les valeurs d’attente correspondent à celles dans l’image de Heisenberg correspondante.   Cette dérivation est réalisée dans un espace-temps plat.


Key words: Tomonaga–Schwinger Equation; Functional Schrödinger Quantization.
