Quantum Identities for the Action
arXiv:1702.05516 · doi:10.1016/j.physleta.2018.02.034
Abstract
In this paper we derive various identities involving the {\it action} functional which enters the path-integral formulation of quantum mechanics. They provide some kind of generalisations of the Ehrenfest theorem giving correlations between powers of the action and its functional derivatives.
