I have problem with that:

Math

How to do that? \supess don't exist, I tried with only {supess} but same - won't compile :/

This is what I have already: {supess}\limits_{0\leq x\leq 2\pi}.

    $\mathop{\mathrm{suppess}}\limits_{0\leq x\leq 2\pi}$ –  Dec 27 '17 at 09:27

    @Herbert Or rather $\mathop{\mathrm{sup,ess}}\limits_{0\leqslant x\leqslant 2\pi}$. However package polski (OP is a Pole) changes inequalities to the Polish version. – Przemysław Scherwentke Dec 27 '17 at 09:30
  • Alternativity using the amsmath package: $\underset{0\leq x\leq 2\pi}{\mathrm{supess}}$ – leandriis Dec 27 '17 at 09:32
  • @PrzemysławScherwentke: maybe, I have no idea what suppess means. –  Dec 27 '17 at 10:34
  • @Herbert if I could know :) I have evaluation work - rewriting part of the math manual :D – Tymoteusz Stępień Dec 27 '17 at 10:40
  • @Herbert It is essential supremum, hence a small space between sup and ess. – Przemysław Scherwentke Dec 27 '17 at 10:43
  • @TymoteuszMaciejStępień So please be aware of Polish typographic rules. BTW: some lessons with Zofia Walczak? (Sorry that in public, but there are no private messages). – Przemysław Scherwentke Dec 27 '17 at 10:46
  • Nope - Agnieszka Sibelska (if you want to know about lessons with tex/linux/webdev) – Tymoteusz Stępień Dec 27 '17 at 10:47
  • @TymoteuszStępień I have just seen her files. You need NOT to be aware of Polish typographic rules. :-( I hope that you are not forced to reproduce horrible mistakes from exercises (na przykład Zadanie 3, Zadanie 4 czy Zadanie 6). – Przemysław Scherwentke Dec 27 '17 at 11:31

  • @PrzemysławScherwentke We done all of this, it's horrible - same as webdev (my passion from primary school, and I have job in this) - I told her it's better ways to do something like this or this, but yeah - she have higher academic degree than me so I just "agree" with that and done what she told us to do. It's end of this exercises so uff. I pass this lessons in her "class" so it's good. – Tymoteusz Stępień Dec 27 '17 at 12:43

You probably want to declare a new math operator:

\documentclass{article}
\usepackage{amsmath}

\DeclareMathOperator*{\supess}{sup\,ess}

\begin{document}

\[
\supess_{0\leq x\leq 2\pi}
\]

\end{document}

enter image description here

This is more convenient than using \operatorname*{sup\,ess} (note that ~ is not the best here), because you may be requested to change the rendering into

enter image description here

(a notation more commonly used in document written in English), which can be accomplished by just changing one line

\DeclareMathOperator*{\supess}{ess\,sup}

without chasing for all appearances in the document.

I would use amsmath and \operatorname. While \mathrm uses normally the same font as the operators, one can be sure that this is true in all math setups. (The star leads to \limits):

\documentclass{article}
\usepackage{amsmath}
\begin{document}

\[\operatorname*{sup~ess}_{0\leq x\leq 2\pi}\]

\end{document}

enter image description here

Variants are to use sup\,ess, and the \leq can be changed too. If needed a command like \supess can be defined with \DeclareMathOperator.

You can use the following:

\documentclass{article}

\begin{document}
\[\mathop{\mathrm{sup~ess}}\limits_{0\leq x\leq 2\pi}\]
\end{document}

with the result:
