Where can I find the integral shown in page 17 of Russian Typographical Traditions in Mathematical Literature ?

I don't know about that particular integral sign, but the Euler math fonts have an upright integral sign and the STIX fonts have variants for its integrals which are upright also.

• @lyashenko You want the german symbol or the russian symbol ? In the texte, I read that German-style integrals are also sometimes seen in Russian literature. Apr 3 '11 at 12:59
• @Iyashenko Ah, I see; sorry for the misunderstanding. I hope that someone creates a nice OpenType Russian-style maths font! Apr 3 '11 at 14:39

This one ??

\documentclass{scrartcl}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{mathabx}

\begin{document}
$\int$
$\int$
\end{document}

• The large symbol is incorrect.

• @lyashenko With mathabx inline and display math symbols are different ! (why ? I don't know) but I don't understand what you want : something like the inline symbol ? because page 17 of your link, and in wikipedia, the russian symbol for integral seems to be a slanted symbol. It's not very easy to found ! Apr 3 '11 at 12:55
• @Miriam.Yeung : a correct large one is probably difficult to make, since the (invert) slope of the central region would depend on its vertical height. Apr 6 '11 at 13:57
