WebTitle: QUANTUM VARIABLES AND THE ACTION PRINCIPLE Full Record Other RelatedResearch Abstract The validity of the action principle is examined for the simplest qunntum degree of freedom, V = 2. It is concluded that the action principle is still severely restricted in a practical sense. Compntations are included. (C.H.) WebSchwinger’s Quantum Action Principle descended from Dirac’s formulation, which independently led Feynman to his path-integral formulation of quantum mechanics. Part I brings out in more detail the connection between the two formulations, and applications are discussed. Then, the Keldysh-Schwinger time-cycle method of
