Hi.
Look at the output produced by the following:
---%<------%<------%<------%<--Cut-Here-%<------%<------%<------%<------
\documentclass{article}
\usepackage{amsmath}
\DeclareMathOperator{\Div}{div}
\begin{document}
The norm of $\Div\mathbf h$ is denoted $\|\Div\mathbf h\|$. The norm of $\nabla\phi$ is denoted $\|\nabla\phi\|$.
\end{document} ---%<------%<------%<------%<--Cut-Here-%<------%<------%<------%<------
There seems to be more space between the lefthand norm symbol and the
"div" than there ought to be. (Compare with the lefthand norm symbol
and the nabla.)
Any explanations for this? Any idea how to fix?
Thanks.
yes, don't use \|, use \lVert and \rVert. As you have noticed \| does not provide the correct spacing. I'm usre one of the experts can give an explanation as to why.
also compare
$|-1|$ to $\rvert -1 \rvert$
