Equivariant symplectic difference schemes and generating functions

Abstract We show that all the known results on the preservation of first integrals by a symplectic difference scheme can be unified under the equivalence theorem of Feng-Ge. In particular, when the equivalence theorem is applied to the first type of generating function on a Lie group, we obtain the Lie-Poisson integrator.
