[O] problem exporting org to latex: sections with math

[Uwe Brauer]

Hello

I export a org file to latex using the exam class and therefore thanks
to Thomas Hunter I have defined.


(org-latex-classes
(quote
 (
  ("exam" "\\documentclass[12pt, addpoints, answers]{exam}"
   ("\\begin{questions}%%%s" "\\end{questions}"
   "\\begin{questions}%%%s" "\\end{questions}")
   ("\\titledquestion[%s]  " . "")
   ("\\begin{parts}%%%s" "\\end{parts}" "\\begin{parts}%%%s"
   "\\end{parts}")
   ("\\part[%s] " . "")
   ("\\begin{subparts}%%%s" "\\end{subparts}"
   "\\begin{subparts}%%%s" "\\end{subparts}")
   ("\\subpart[%s] " . "")
   ("\\begin{solution}[%s]" "\\end{solution}" "\\begin{solution}[%s]"
   "\\end{solution}")))))

The problem is that my document also contains latex \section commmands.
These are exported correctly *only* if they don't contain math.

Works
\section{Adaptive methods using  hopt}

Does not work:
\section{Adaptive methods using  $h_{\text{op}}$}


The resulting latex file looks like

Ok
\section{Adaptive methods using  hopt}

The following is not ok,

\section\{Adaptive methods using  \(h_{\text{op}}\)\}


So what shall I do?

Thanks regards
