To my understanding this does add support for indices with coordinate systems, but probably not in a rigorous way.
I see. To me as an engineering student, physics and Riemannian geometry are basically the entire universe. I didn't find the
tensor
module to be overly complicated to use, for what it's worth.I tried that module first, but I don't have any background in differential geometry and I didn't understand how I could use it to solve problems like this. I asked the mailing list and didn't get much help, so I wrote this.
Unfortunately I am ignorant of the extent of my own ignorance of this subject, so I'm not qualified to speculate on whether or not this would be good for SymPy. I assume I have made some crucial mistakes in my assumptions that would not be appropriate for the level of generality desired for the
tensor
module. If not, I would be happy to submit a pull request.
