# Is there that kind of symbol? [duplicate]

Is there a way to use that kind of symbol?

• This is \drsh from mathabx or \Rdsh from fdsymbol or stix. – Bernard Sep 5 '18 at 17:44

You could use arrows from mathabx, but not the whole package that changes all math symbols in a way that could not be desirable. See https://tex.stackexchange.com/a/273044/4427 for part of the code.

\documentclass{article}
\usepackage{amsmath}

\DeclareFontFamily{U}{mathb}{}
\DeclareFontShape{U}{mathb}{m}{n}{
<-5.5> mathb5
<5.5-6.5> mathb6
<6.5-7.5> mathb7
<7.5-8.5> mathb8
<8.5-9.5> mathb9
<9.5-11.5> mathb10
<11.5-> mathb12
}{}
\DeclareSymbolFont{mathb}{U}{mathb}{m}{n}
\DeclareMathSymbol{\ulsh}{3}{mathb}{"E8}
\DeclareMathSymbol{\ursh}{3}{mathb}{"E9}
\DeclareMathSymbol{\dlsh}{3}{mathb}{"EA}
\DeclareMathSymbol{\drsh}{3}{mathb}{"EB}

\begin{document}

$a\drsh b$

$a\dlsh b$

$a\ursh b$

$a\ulsh b$

\end{document}

• There is a typo in DeclareFontShape: mathbb12 should be replaced with mathb12, as spotted in the quoted answer. – Andrey Popov Sep 13 '19 at 11:53
• @AndreyPopov Fixed, thanks – egreg Sep 13 '19 at 12:20

Yes it is possible:

\documentclass{article}
\usepackage{mathabx}
\begin{document}

$A \drsh B$

\end{document}
