Riemann Normal Coordinate expansions using Cadabra

General Relativity and Quantum Cosmology 2022-11-07 v3

Abstract

Riemann normal coordinate expansions of the metric and other geometrical quantities, including the geodesic arc-length, will be presented. All of the results are given to fifth-order in the curvature and were obtained using the computer algebra package Cadabra.
