广义相对论张量计算工具Cadabra简介

A brief introduction to Cadabra: a tool for tensor computations in General Relativity

Leo Brewin

摘要:

Cadabra是一个强大的计算机程序,用于处理张量方程。它被设计用于高能物理,但其丰富的结构和易用性使其本身很好地适用于广义相对论所需的例行计算。在这里,我们将提出一系列简单的例子,显示如何Cadabra可以使用,包括验证列维-奇维塔连接是一个度量连接和诱导和环境曲率之间的高斯方程的推导。

英文摘要:

Cadabra is a powerful computer program for the manipulation of tensor equations. It was designed for use in high energy physics but its rich structure and ease of use lends itself well to the routine computations required in General Relativity. Here we will present a series of simple examples showing how Cadabra may be used, including verifying that the Levi-Civita connection is a metric connection and a derivation of the Gauss equation between induced and ambient curvatures.
