I am just wondering, is there a difference in meaning/definition between the indices of a tensor being right on top of each other
[tex]A_{\mu }^{\nu }[/tex]
and being "spaced" as in
[tex]A{^{\nu }}_{\mu }[/tex]
I seem to remember that I once read that there is indeed a difference, but I can't remember what it was.
Thanks in advance.
