摘要: We study the effect of an infinitesimal coordinate transformation on Lagrangian and metric functional a system ofn point masses. show how to compute Lagrangians masses at second postNewtonian approximation general relativity in different systems. The are shown depend accelerations except special class coordinates. This includes coordinates associated with canonical formalism Arnowitt, Deser, Misner, but excludes most other systems used literature (notably harmonic one).
