How should I refer to sections and equations?

The class inserts internal and external hyperlinks into the PDF using the package hyperref. To give a more visible “target” for internal links, hyperref provides the command \autoref.

Therefore, label with \label as usual any text element you wish to link to (section, table, figure, theorem, etc.), and then create the reference with \autoref. The command \autoref automatically provides the description label for the reference, and this becomes part of the link. For example:

see \autoref{tab:results} for the complete results

The exception to this rule is equations. Cite equations using the command \eqref and choose an appropriate description (“equation”, “inequality”, “relation”, etc.). Use an unbreakable space between the description and the reference:

equation~\eqref{eq:definition}
