DESCRIPTION:The talk concerns Hamiltonian systems with a Lie group symmetr
 y\, that are conjugate to a variational problem. The motivation for the ta
 lk includes recent results of the speaker with Tania Goncalves\, which sho
 w the structure of the set of conservation laws arising from Noether's The
 orem in terms of invariants and a moving frame. We exhibit a simple explic
 it formula for the moment map for the related Hamiltonian system\, in both
  smooth and discrete cases\, and discuss the application of the Fels and O
 lver reformulation of the moving frame to the integration problem.\n
