I am just wondering, is there a difference in meaning/definition between the indices of a tensor being right on top of each other(adsbygoogle = window.adsbygoogle || []).push({});

[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.
