How to place text as subscript under mathematical operator in equation?

Question

I would like to put some text in math mode below a mathematical operator (or a symbol), similar to substack in sum, as the red text below the max operator in the following image

How to do this?

You should place the expression in the subscript, as shown below. Most LaTeX books explain this. E.g.
documentclass{article}

begin{document}
begin{itemize}
    item textbf{Display mode}:
        [max_{1 leq i leq N}]
    item textbf{Inline mode}: version without verb!limits! would look like (max_{1 leq i leq N}), version with verb!limits! would look like(maxlimits_{1 leq i leq N}) inside a text.
end{itemize}
end{document}

Note how limits command force the subscript under operator in inline mode (if you think you need limits, think again — maybe the defaults look better after all! cf. this answer here on TeX.se).
If you find that the subscripted expression is too long and introduces excessive whitespace, you could use smashoperator macro from the mathtools package, as in this post.

I would solve it like this:

documentclass{scrartcl}
usepackage{amsmath}
begin{document}  
[
    maxlimits_{1leq jleq n}
]  
end{document}

Solved this for Inline mode by using $underset{1 leq j leq n}{max}$, however this approach requires the amsmath package.

As someone suggest above. We should use underset command:
underset{1leqslant jleqslant n}{max}.

underset{substack{rhoto 0 ntoinfty}}{l.i.m.}

(for my question above).
