J. Schwinger, Phys. Rev. 82, 914 (1951). Imposing the surface condition in Eq. (1) on Schwinger’s principle of stationary action is equivalent to augmenting the Lagrange function operator in such a way as to lead to a class of generators whose associated infinitesimal transformations yield variations of the action-integral operator for an open system that are similar in form and content to those obtained for a total isolated system. Schwinger applied his principle to a total system by varying the time and the field variables in the spacelike surface (which corresponds to the system at a given time) at the two time end points. However, the general statement of his principle, as given in his Eq. (2.19), allows for corresponding variations of the timelike surface (varying the spatial boundary of an open system for each time) and for variations of the field variables in this surface, thereby enabling one to define the quantum mechanics of an open system Ω.
