I’ve just updated the SAGE worksheet which uses the definitions described in the previous posts.
Moreover… I’ve discover something really amazing! Joris Vankerschaver‘s code of the differential form package in SAGE. Thus, I could use some ideas from Joris’ code to improve GRmodule. Nice, Isn’t it?
Let’s hope I could so something nice this weekend!
Don’t forget check the worksheet, and post some comment for feedback! 😉
