Weak-field approximations and equations of motion in general relativity
Description
Before considering approximation methods I shall discuss the concept of an isolated system since a discussion of approximation methods is meaningful only if one knows what is to be approximated. Then Einstein's equation will be replaced by a reduced field equation susceptible to successive approximations, and a local equation of motion. This is followed by an outline of one version of a 'fast' or Poincare-invariant approximation method, and by one of a 'slow' or quasistationary approximation method. (orig.)

Bevor Naeherungsmethoden betrachtet werden, wird das Konzept eines isolierten Systems diskutiert, da eine Diskussion von Naeherungsmethoden nur dann sinnvoll ist, wenn man weiss, was anzunaehern ist. Anschliessend wird die Einstein'sche Gleichung durch eine reduzierte Feldgleichung, die sukzessiv angenaehert werden kann, und durch eine lokale Bewegungsgleichung ersetzt. Darauf folgt ein Entwurf einer Version einer 'schnellen' oder Poincare-invarianten Approximationsmethode, und danach eine der 'langsamen' oder quasistationaeren Naeherungsmethoden.
