Time dependent canonical transformations and the symmetry-equals-invariant theorem
Time dependent canonical transformations and the symmetry-equals-invariant theorem
Expressions for the remainder function of a time dependent infinitesimally generated canonical transformation have recently been found by Dewar, who considered the action of the transformation operators on Liouvilleās equation. Here an alternate proof of the remainder function expression is given, based on the transformations of particle trajectories. Then, using ā¦
