摘要
In this paper we present the coefficients of several sixth-order symplectic integrators of the type developed by R. Ruth. To get these results we fully exploit the connection with Lie groups. These integrators, as well as all the explicit integrators of Ruth, may be used in any equation where some sort of Lie bracket is preserved. In fact, if the Lie operator governing the equation of motion is separable into two solvable parts, the Ruth integrators can be used. © 1992.
