Description

Abstract We report on a package of routines for the computer algebra system Maple which supports the explicit determination of the geometric quantities, field equations, equations of motion, and conserved quantities of General Relativity in the post-Newtonian approximation. The package structure is modular and allows for an easy modification by the user. The set of routines can be used to verify hand calculations or to generate the input for further numerical investigations. Title of program: Procrustes Catalogue Id: ADYH_v1_0 Nature of problem The post-Newtonian approximation represents an approximative scheme frequently used in General Relativity in which the gravitational potential is expanded into a series in inverse powers of the speed of light. Depending on the desired approximation level the field equations and equations of motion have to be determined up to given orders in the speed of light. This usually requires large algebraic computations due to the geometrical quantities entering the field equations and equations of motion ...
