When using a special TeX command in titles or captions, these will be used by hyperref, and they must then be prevented to expand wrongly if they are not robust commands by using protect in front of them.
For example, given \newcommand{\GJ}{\mathcal{J}} if we want to set into a title \section{The $\GJ$ relation}, we need to write instead \section{The $\protect\GJ$ relation}.
