General ⇒ subsection includes mathematical symbols - a warning

[pallav]

The below line gives a warning in latex:

Code: Select all

\subsection{Global stability of $E^*(x^*,y^*,z^*)$.}

I want to remove the warning. I want to get a subsection where its heading includes mathematical symbols.

What are the warnings? I get non with report class using your subsection title.

Can you post an MWE and the warning message.

I got 6 warning for this.

I got 6 warning for this.

This is a trivial statement. Be more specific. The exact wording can be retrieved from the log file.

The warnings are caused by the hyperref package, which doesn't like math expressions in headings when generating the bookmarks for the document. Search the manual for the \texorpdfstring command to fix this problem.
