Suppose you have a mathematical paper titled

All functions are $C^\infty$

What is the best way to deal with such a situation when citing such a title in bibtex? Does bibtex cope with mathematics in entries?

There's nothing special to do, other than protecting the math with braces to avoid BibTeX making it lowercase.

As usual, in the example I use the filecontents* environment to get a self-contained document; you can normally use your .bib file.

 author={B. C. Dull},
 title={All functions are {$C^{\infty}$}},
 journal={J. False Results},

Dull proved a sensational result in~\cite{nice}.
