Sub-indexes
I need to put an index under a symbol that is not \sum.

For instance: {i=1} must go under the symbol, not as regular subscript.

\sum_{i=1} does that but I need to see the same under other symbols.

Any idea?

Thanks.

Hm, I'm not sure if this will answer your intended question but I know there are some commands where you can put a substrict "underneath" like
"min" would be

Latex code would be
Code:

\min_x
Other commands include dim, gcd, Pr, inf, max, sup, limsup, liminf, and several more.

Thanks, but...
It's exactly what I need and I'm trying.

Unfortunately what you suggested does not work on my LaTex.

x comes out as regular, right subscript in \min_x

Are you looking for something like this:

${\rm {XYZ} \atop {x=5}} = \sqrt{\frac15}$

Maybe you can alter the size in the subscript line(?)

Functions like \min \max \sum take the subscript below their symbol when the equation is within $...$.

They take it as a regular right-lower subscript when the equation is within $...$.

Thanks for all replies!
