For very strange reasons, the slot "6B in the font sy-iwona is empty. The \lVert and \rVert commands point to that slot, so you can't see any symbol because it's not there to begin with. The definition of \lVert and \rVert given by amsmath are \DeclareMathDelimiter{\lVert} {\mathopen}{symbols}{"6B}{largesymbols}{"0D} \DeclareMathDelimiter{\rVert} ...

EDIT for left/right. While David Carlisle points out that my solution does not work for vertically scaled \left \right syntax, the \stretchleftright{}{}{} syntax of the scalerel package takes care of it. \documentclass{standalone} \usepackage[math]{iwona} \usepackage{mathtools} \usepackage{scalerel} \DeclarePairedDelimiter\norm{\lVert}{\rVert} ...

Just a suggestion. \documentclass[preview,border=12pt]{standalone}% change to your document class \begin{document} $C\left(\frac{1}{n}\sum_{i=1}^n x_i\right) = C(x_j)$ where $j=1,\ldots,n$. \end{document}

I've often wondered why some symbol or operator doesn't have a name, when it seems to be so common in my papers ("Hom" being the big offender...who doesn't use this?!). The fact is, however, that there are practically an enormous number and potentially an infinite number of mathematical operator names, and as David Carlisle observes in his answer, at the ...

With some juggling of the different math classes it's possible to achieve what you want: \documentclass{article} \newcommand*\mixedmath[3]{% #1{#3}% \ifx#1\mathbin \nonscript\mskip-\medmuskip \mathord{}% \fi \ifx#1\mathpunct \nonscript\mskip-\thinmuskip \fi \mathclose{}\mathopen{}% \ifx#2\mathbin \mathord{}% ...

There is no solution in general as the space that is added between each adjacent math class is fixed in TeX (luatex allows it to be changed) For any given expression, rather than deeply nested \math... commands you can simply add the space that TeX would have added had the class been different (which will be \thinmuskip, \medmuskip or \thickmuskip). The ...

I don't think there is a unique proper way of doing this. There is the operator $\min$ which might be appropriate here. In order to define your own operators, consider using \DeclareMathOperator{\Minimum}{Minimum} from amsmath to be able to use $\Minimum U_\mathrm{res}$. Using the operator will give you suitable spacing around the operator, just as you ...
