How to use tensors in Mathematica?

Ji?í Ryzner

Posted 13 years ago

Hello everybody, I am beginner in Mathematica. I would like to know how to use tensors in Mathematica in general relativity, i.e. when i have defined metric tensor, how to compute tensors that appear in Einstein and Maxwell equations and get exact form of both sides; lowering/uppering four-vectors, covariant derivate etc. Is it built in or is some package needed? Thank you for any answer.

With the release of version 14.3, examples using the new functions FindShortestCurve and ShortestCurveDistance have been added." Attachments: msh_tensorial.wl msh_tensorial20251031.nb

"Tensorial Analysis" was originally developed by Renan Cabrera and later modified by Munehiro Shinabe (shinabe.munehiro@hotmail.co.jp). This tensor calculus package is designed for beginners and is well-suited for studying in reference to standard textbooks. Its beautifully formatted equations follow the notation commonly used in academic texts.

Title: "Tensor Analysis and Calculus" msh_tensorial20241202.nb is a notebook file created for beginners to help them understand introductory books on tensors. The "msh_tensorial.wl" package is easy to use with good-looking mathematical expressions. Attachments: msh_tensorial.wl msh_tensorial20241202 .nb
