plus in superscript.

plus in superscript.

[Piter_]

Hi all. I try to put a superscript in org-mode in this way: T^{+}. But
it gets exported in latex as $^{\st{}$.  Any idea how to avoid it?
Thanks.

{Super,sub}scripts are latex math constructs - try the following:

--8<---------------cut here---------------start------------->8---
* This is a test: \(T^{+}\)

And inline: \(T^{+}\) and displayed: \[T^{+}\]
--8<---------------cut here---------------end--------------->8---

But latex subscripts/superscripts should work in Org even without an 
explicit math environment, and they do for me -- exporting Piter's 
T^{+} gives me

T$^{+}$

as expected. Something in his setup?

You are right - sorry about the noise.

Apart from what Christian said, do you have any comments about $..$
and \(..\) ? I hear conflicting arguments about which is preferred
(e.g. $..$ is a TeX construct where as \(..\) is a LaTeX macro arguing
in favour of $..$). Specially an opinion in the context of org ->
latex export would be interesting to hear.

As far as LaTeX is concerned, I believe that $...$ and \(...\) are
entirely equivalent (but you have to use \[...\], and not $$...$$ for
displayed material). That's from reading Lamport's book: sec 3.3 and
Appendix E (the "Miscellaneous" section); I have not checked the code.

I prefer \(...\) and (iirc) sometimes that has worked when $...$ has
not, but I don't remember the context; afaik those (rare) situations
were deemed to be bugs in the exporter and have all been fixed.

Hi,

$...$ may sometimes get confused with currency signs, variable names 
and whatnot.

Org-mode is sophisticated about it as long as you follow a few 
safeguards -- from the Info section 11.7.3:

      To avoid conflicts
      with currency specifications, single `$' characters are only
      recognized as math delimiters if the enclosed text contains at
      most two line breaks, is directly attached to the `$' characters
      with no whitespace in between, and if the closing `$' is followed
      by whitespace, punctuation or a dash.  For the other delimiters,
      there is no such restriction, so when in doubt, use `\(...\)' as
      inline math delimiters.

But note that MathJax, the preferred backend for math in Org's HTML 
exports, does not support $...$ by default. To configure it, see:

http://www.mathjax.org/docs/1.1/tex.html#tex-and-latex-math-delimiters

Yours,

Christian

When Org exports to HTML for use with MathJax, it does convert $..$ to \(..\) to work around this.

Still, parsing $...$ is much harder than parsing \(..\), so most of the time, using \(//\) will give better and more stable results with Org-mode.

Oops, I should have guessed. I just remembered having to fiddle with 
my MathJax configuration at one point, but that was probably before 
Org even switched from dvipng to MathJax as default.

And a good deal more readable.
