What is the mathematical notation for Convex Hull?

Generally speaking, the notation used in an article is set by the author who is somewhat obliged to use standard notations (as prescribed by any recognized publisher) unless the document has become so notationally heavy that certain things must be avoided. Conv$\,(\cdot)$ fairly standard for the convex hull as it does not interfere much with other potential notations.

I am used to the notation $\operatorname{Conv}(\cdot)$, but you can really use whatever you like as long as you explain the notation.
