TITLE: What is the mathematical notation for Convex Hull?
QUESTION [8 upvotes]: I've been scanning through scientific papers, this site and just googling for it, but I can't find a commonly accepted notation for the convex hull.
So my question is; if there is, what is the standard notation for convex hull?
Seems to me people just use their favorite out of a large collection of notations (or invent their own notation) to denote the convex hull of, say $S$, including
\begin{align}
\mathrm{conv}(S),\ \mathrm{CH}(S),\ \mathrm{conv.hull}(S),\ \mathrm{Co}(S),\ \mathrm{C}(S),
\end{align}
which I find frustrating. :)

REPLY [2 votes]: I've seen $\mathrm{Hull}(\cdot)$ used pretty often; I think Michael Kapovich uses it in his papers. Unless there's another usage of hull in mathematics that I'm not aware of, it's a pretty safe and easy to understand notation.
