Hamiltonian dynamics on the symplectic extended phase space for autonomous and non-autonomous systems

Abstract: We will present a consistent description of Hamiltonian dynamics on the "symplectic extended phase space" that is analogous to that of a time-independent Hamiltonian system on the conventional symplectic phase space. The extended Hamiltonian H 1 and the pertaining extended symplectic structure that establish the proper canonical extension of a conventional Hamiltonian H will be derived from a generalized formulation of Hamilton's variational principle. The extended canonical transformation theory then naturall… Show more

“…(See [5,7,12,14,16] for more details). In the jet bundle description of non-autonomous dynamical systems, the configuration bundle is π : E / / R, where E is a (n + 1)-dimensional differentiable manifold endowed with local coordinates (t, q i ), and R has t as a global coordinate.…”

“…One basic idea towards a geometric discretization [8,10,13] of this type of equations is first to introduce an spatial truncation, that reduce the PDE (16) to a system of ODEs preserving many of its geometrical properties. Hence, we replace the x-derivative in the Lagrangian by a simple difference (for simplicity, we will work with a uniform grid of N + 1 points, h = K/N ) as follows:…”

“…The Nosé-Poincaré thermostat, which is the Hamiltonian version of Nosé-Hoover thermostat, utilizes the Poincaré time transformation H = ν(H − H) where ν is the time scaling factor and H is the value of H regarded as a pure function of time [9]. This permits the description of Hamiltonian dynamics in the symplectic extended phase space.…”
