The mathrsfs package provides \mathscr for script mathematical letters, rather than redefining \mathcal:

\documentclass{article}
\usepackage{mathrsfs}% http://ctan.org/pkg/mathrsfs
\begin{document}
$\mathscr{L}u$
\end{document}

enter image description here

Also consider reading this entry on the UK TeX FAQ: Better script fonts for maths.

Thanks. (I keep forgetting about the TeX FAQ. I should stop doing that.) –  rogerl Aug 28 '11 at 16:42
