Symmetric multistep methods for constrained Hamiltonian systems
P. Console, E. Hairer, and C. Lubich
Abstract. A method of choice for the long-time integration
of constrained Hamiltonians systems is the Rattle algorithm. It is
symmetric, symplectic, and nearly preserves the Hamiltonian, but it is
only of order two and thus not efficient for high accuracy requirements.
In this article we prove that certain symmetric linear multistep methods
have the same qualitative behavior and can achieve an arbitrarily
high order with a computational cost comparable to that of the Rattle
algorithm.
Key Words. Symmetric multistep methods, constrained Hamiltonian
systems, Rattle algorithm, backward error analysis, parasitic solution components.
