[tex]R_{[abc]}[/tex]

and also things like:

[tex]\nabla_{[a\nabla_b]}[/tex]

Where you have square brackets in the subscript? Thx

For example,

[tex]A_{[ab]}=\frac{1}{2}(A_{ab}-A_{ba})[/tex]

Ah yes, thanks matterwave, I guess (ab) is the symmetric part then

[tex] F_{\mu\nu}=2\partial_{[\mu}A_{\nu]} [/tex]

while others

[tex] F_{\mu\nu}=\partial_{[\mu}A_{\nu]} [/tex]

in case of the e-m fields.
