Abstract:The numerical integration of Hamiltonian systems by symplectic modified partitioned Runge-Kutta methods with the trigonometrically fitted property is considered in this paper. We construct new symplectic modified Runge-Kutta method of second order with the trigonometrically fitted property. We apply our new method as well as other existing methods to the numerical integration of the harmonic oscillator, the two dimensional harmonic oscillator, the two-body problem and an orbit problem studied by Stiefel and Be… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
