Tensor calculus with open-source software: the SageManifolds project (1412.4765v2)
Published 15 Dec 2014 in gr-qc, hep-th, math-ph, and math.MP
Abstract: The SageManifolds project aims at extending the mathematics software system Sage towards differential geometry and tensor calculus. Like Sage, SageManifolds is free, open-source and is based on the Python programming language. We discuss here some details of the implementation, which relies on Sage's parent/element framework, and present a concrete example of use.
