Noether's theorem and Lie symmetries for time-dependent Hamilton-Lagrange systems
Jürgen Struckmeier, Claus Riedel
Noether and Lie symmetry analyses based on point transformations that depend on time and spatial coordinates will be reviewed for a general class of time-dependent Hamiltonian syst…

Invariants for time-dependent Hamiltonian systems
Jürgen Struckmeier, Claus Riedel
An exact invariant is derived for -degree-of-freedom Hamiltonian systems with general time-dependent potentials. The invariant is worked out in two equivalent ways. In the first…
