# Wedge with vertical bar

I'm making a summary sheet of a course in LaTeX. There are, however, I have no idea how to draw two of the symbols. One of them is some sort of \wedge with a vertical bar through it, the other a \vee with a vertical bar through it, as shown below:

Any ideas how I could compose such a symbol?

-

This overlaps three things: wedge/vee, shortmid, and shortmid raised to a correct height. The numbers suit cm and lm fonts, for other fonts they might need to be modified.

See here for a quick course on \ooalign.

\documentclass{article}
\usepackage{amssymb}

\makeatletter
\newcommand\@@vertwv[3]{\mathop{\ooalign{%
$#1#3$\cr
\hfil$#1\shortmid$\hfil\cr
\hfil\raisebox{#2}{$#1\shortmid$}\hfil\cr}}}
\newcommand\@vertwv[1]{\mathchoice
{\@@vertwv{\displaystyle     }{0.38ex}{#1}}%
{\@@vertwv{\textstyle        }{0.38ex}{#1}}%
{\@@vertwv{\scriptstyle      }{0.28ex}{#1}}%
{\@@vertwv{\scriptscriptstyle}{0.21ex}{#1}}}
\newcommand\vertwedge{\@vertwv\wedge}
\newcommand\vertvee  {\@vertwv\vee  }
\makeatother

\begin{document}

$a\vertwedge b \neq a\vertvee b$
$\textstyle a\vertwedge b \neq a\vertvee b$
$\scriptstyle a\vertwedge b \neq a\vertvee b$
$\scriptscriptstyle a\vertwedge b \neq a\vertvee b$

\end{document}

Just what I needed, thanks :) –  Saew Jan 9 '13 at 16:41

For users of XeLaTeX and LuaLaTeX exist with the unicode-math package and the fonts XITS Math, Asana Math and (according to the unciode-math symbol list) Lucida Math the macros

• \veemidvert and
• \wedgemidvert

to access these symbols.

## Code

\documentclass{article}
\usepackage{amsmath}% not needed but used for this example and the align environment
\usepackage{unicode-math}
\setmathfont{XITS Math}
%\setmathfont{Asana Math}
\begin{document}
\begin{align*}
x \veemidvert y \leq z & \equiv x \leq z \wedge y \leq z \\
z \leq x \wedgemidvert y & \equiv z \leq x \wedge z \leq y
\end{align*}
\end{document}


## Output

The top rows show XITS Math, the bottom ones show Asana Math.
