Symplectification of truncated maps for Hamiltonian systems

Serge Andrianov

Mathematics and Computers in Simulation (MATCOM), 2001, vol. 57, issue 3, 139-145

Abstract: The time–displacement operator for Hamiltonian dynamical systems M(t|t0) is a symplectic transformation — Lie map. Any truncated Lie map (Lie approximant) loses the very important symplectic property.
