I. What does
A_{[\alpha} B_{\beta]}
mean? How do you expand this?
II. How do you put TeX in board posts?

dextercioby said:It's not necessary to use the numerical factor (we call it "weght"). See for example the em. tensor in vacuum. U can use the "no number convention" (i use it)
[tex] F_{\mu\nu}\equiv F_{\left[\mu\nu\right]}=:\partial_{[\mu}A_{\nu]} [/tex]
or the one Rob exemplified, when an ugly 2 comes up
[tex] F_{\mu\nu}\equiv F_{\left[\mu\nu\right]}=:2 \partial_{[\mu}A_{\nu]} [/tex]

dextercioby said:I didn't in any place claim that
[tex] F_{[\mu\nu]}=F_{\mu\nu}-F_{\nu\mu} [/tex]
So no inconsistency. Whatsoever.

The purpose of expanding subscripts and putting TeX in board posts is to allow for more advanced mathematical and scientific notation in online discussions and forums. This can help clarify and accurately communicate complex equations and formulas.
To use expanding subscripts, you can enclose the subscript in curly braces, followed by an underscore. For example, typing "H{2}O" will display as H2O in your post.
No, not all online forums and discussions support TeX. It is important to check the forum's guidelines or formatting options to see if TeX is supported before attempting to use it in your posts.
Yes, there are many online resources and guides available for learning how to use TeX in board posts. Some popular resources include the TeX Users Group (TUG) website, which provides a comprehensive guide and tutorials for beginners, as well as various online communities and forums dedicated to TeX and LaTeX.
Yes, you can use various commands and packages in TeX to customize the appearance of equations and formulas in your board posts. This allows for more flexibility and creativity in presenting your mathematical and scientific notation.
