How to indicate supremum or infimum?
In Latex it is “t= sup_{T}”.
In LibreOffice Math, sup is a modifier which makes the subsequent element a superscript.
You may need to open the code editor pane, which is often minimized. Click the tiny triangle in the middle of the bottom border of the preview pane.
To force verbatim display “sup”, you need to quote it.
t="sup"_{T}
If you need it rendered in italics, use the ital modifier.
t=ital "sup"_{T}
For a single element, the braces aren’t really necessary, but they do no harm, and some find the code easier to read when you use that.
CAUTION! _ may not have the same semantics in Math as in LaTeX. In Math _ is a command for subscript. Therefore, the correct formula may be t = "sup" T without the underscore.
