I think I will add a warning in TensMul's docstring about this possible issue.
By the way, Krastanov already pointed out an example on how to deal with General Relativity with the diffgeom module. That is an interesting approach, I wish one day we could have tensor and diffgeom to easily interact with each other. http://krastanov.files.wordpress.com/2012/07/schwarzschild.pdf -- You received this message because you are subscribed to the Google Groups "sympy" group.
