Spinors: A Mathematica package for doing spinor calculus in General Relativity

Abstract

The Spinors software is a Mathematica package which implements 2-component spinor calculus as devised by Penrose for General Relativity in dimension 3+1. The Spinors software is part of the xAct system, which is a collection of Mathematica packages to do tensor analysis by computer. In this paper we give a thorough description of Spinors and present practical examples of use. © 2012 Elsevier B.V. All rights reserved.
