Euler and multicharacter math identifiers
Vladimir Klebanov
I've found a couple of old threads but nothing conclusive on correct
typesetting of multicharacter operators and variables with Euler. With CM
math it is customary to use \mathit{} for both in my domain (logics). This
is not an option with Euler, since Euler (by design) does not have italics.
It was suggested to use \mathrm{} for operators, but what about longer
variables? I cannot imagine to use roman text there. Any suggestions?
Thanks.
Vladimir

\mathit uses the text-mode italic font. So it should work even
if Euler is the math font. However, you should post a complete,
but minimal, example and explain what is wrong with what \mathit
produces.
This works fine for me:
\documentclass{article}
\usepackage{palatino}
\usepackage{eulervm}
\begin{document}
Math example: $f \in \mathit{BMO}$ and $x \ne \mathit{abs}(x)$
\end{document}

Thanks for answering. This does indeed work for operators. But what
about variables?
\documentclass{article}
\usepackage{palatino}
\usepackage{eulervm}
\begin{document}
Math example: for all~$x$,$y$, and~$\mathit{pos}$, such that\ldots
\end{document}
Here x and y are Euler (and thus upright), while pos is palatino italics.
Writing just $pos$ produces p*o*s, of course.
Best,

As I have already said, that is what \mathit _always_ does and what
it
is supposed to do: provide the text-mode italic font inside math (just
as
\mathrm provides the text-mode roman font inside math).
And then I asked you to explain what is wrong with that? That is the
traditional way to designate multiletter identifiers in math.

If you want a more slanted version of the Euler font, it doesn't
exist. Just as there is no upright version of the computer modern
math letters font.

I accept that. ;)

Yes, CM math. The multi-letter type has to be consistent with single-letter
identifiers. Using \mathit for Euler variables breaks this invariant.

No, I do not want this. Again, writing $pos$ adds extra spacing between
letters to make it look like a product. I want a way to typeset several
letters (in upright Euler type) without that additional space.

Euler fonts are being reworked upon, and the new release will have a euler
text font, so you could use that for writing multicharacter variable
names. I do not know if the alpha/beta release of euler fonts are
available anywhere for testing.
