... transformations, which are related to a constant of motion that depends explicitly on the time (see Sec. 3.1, below). The aim of this paper is to show that, with an appropriate definition of the invariance of a Hamiltonian [that generalizes Eq. (2)], any conserved operator is associated with a group ...
