Abstract:
Some characterizations for symmetric multistep Runge-Kutta(RK)methods are ob-tained.Symmetric two-step RK methods with one and two-stages are presented.Numer-ical examples show that symmetry of multistep RK methods alone is not sufficient forlong time integration for reversible Hamiltonian systems.This is an important differencebetween one-step and multistep symmetric RK methods.
