GHP: A maple package for performing calculations in the Geroch-Held-Penrose formalism. (English) Zbl 0986.83028
Authors’ abstract: We present a new symbolic algebra package, written for Maple, for performing computations in the Geroch-Held-Penrose formalism. We demonstrate the essential features and capabilities of our package by investigating Petrov-D vacuum solutions of Einstein’s equations.
