What's the symbol for the curly D used to denote a dissection for a Riemann integral?

Question

In an analysis lecture today the lecturer used the following curly D symbol to denote a dissection (for a Riemann integral):

curly D symbol

How can I get this symbol with LaTeX? I've tried to find it in the comprehensive symbol list, as well as with Detexify, but haven't succeeded.

Have you tried Detexify? Detexify is listed in How to look up a symbol or identify a math symbol or character? — Werner, Feb 24 '15 at 22:13

checking on google for "riemann integral dissection", it appears that there are two different opinions about this. some authors use an ordinary "D" (italic because it's math), and some use a calligraphic form \mathcal{D}. under the circumstances, this seems to be more suited to a math forum than to tex.sx. — barbara beeton, Feb 24 '15 at 22:21

A collection of three possible symbols, just propositions

\documentclass{article}


\usepackage[mathscr]{euscript}

% Copied from mathrsfs.sty
\DeclareSymbolFont{rsfs}{U}{rsfs}{m}{n}
\DeclareSymbolFontAlphabet{\mathscrsfs}{rsfs}

\begin{document}

\huge

$\mathcal{D}$


% Euscript
$\mathscr{D}$


% Ralph Smith's font (mathrsfs.sty)
$\mathscrsfs{D}$

\end{document}

i've no complaint about either of these suggestions, but see my comment on the question regarding what shows up in published references as found through a google search. notation is often a slippery, subjective creature. it may take a practitioner in the particular field to give an authoritative answer. – barbara beeton Feb 24 '15 at 22:23

@barbarabeeton: Your comment appeared after my answer, the later just being a suggestion – Feb 24 '15 at 22:24
