I'm creating a presentation in Beamer which uses the split theme. If I use math mode in a subsection title, then I get error message when compiling the file. The same does not happen for the section titles. A minimal example is given below:

\documentclass{beamer}

\useoutertheme{split}

\begin{document}
\section{A title}
\subsection{\texorpdfstring{\(\Delta\geq6\)}{Delta at least 6}}
\begin{frame}

\end{frame}
\end{document}

Note that you need to run LaTeX twice to produce the error.

  • Strange. I get the following error: line 10: Bad math environment delimiter. \end{frame} followed by several more errors. This is the version I'm using: This is pdfTeX, Version 3.1415926-2.5-1.40.14 (TeX Live 2013/Debian) (format=pdflatex 2014.10.3)

    Texlive 2013 is toooo old. You may have to update.

Using $ for math mode works (with pdflatex):

\subsection{\texorpdfstring{$\Delta\geq6$}{Delta at least 6}}
