[tomasb47]

Dear All,

If I write $$\sup_y$$, Latex will produce a formula with "y" centered under the text string "sup".
Is there any way I can write a formula replacing the string "sup" by some
other string, for example by "maximize"? I can of course write $$\max_y$$
but I really want the string to be "maximize" and/or "minimize", and I want "y" to be centered under "maximize".
If I write $$\mbox{maximize}_y$$ then "Y" will only be a subscript. I cannot use $$\stackrel$$ since then I will
get the "y" above "maximize", and if I change the order then "maximize" will be out of line (above the main text line).
Hoping for help

Hi Tomas,

welcome to the forum!

You could use \DeclareMathOperator* of amsmath:

Code: [Select all] [Expand/Collapse] [Download] ({untitled.tex}) Open in Overleaf

\documentclass{article}
\usepackage{amsmath}
\DeclareMathOperator*{\maximize}{maximize}
\begin{document}
$$\maximize_y$$
\end{document}
