LaTeX symbol for the Kulkarni-Nomizu product
You can combine \bigcirc
with \wedge
.
Of course, you can also create and use a new command. The result is, obviously, the same with or without the new command.
Edit:
However, with \mspace
the symbol becomes misaligned when used in \scriptstyle
or - worse - in \scriptscriptstyle
.
\documentclass{article}
\usepackage{amsmath, amssymb}
% Of course, you can create...
\newcommand{\KN}{\mathbin{\bigcirc\mspace{-15mu}\wedge\mspace{3mu}}}
\begin{document}
\[
h \mathbin{\bigcirc\mspace{-15mu}\wedge\mspace{3mu}} k
\]
% ... and use a new command:
\[
h \KN k
\]
\[
x_{h \KN k}
\]
\[
y_{x_{h \KN k}}
\]
\end{document}
See the output:
A solution with \ooalign
.
\documentclass{article}
\makeatletter
\newcommand*\owedge{\mathpalette\@owedge\relax}
\newcommand*\@owedge[1]{%
\mathbin{%
\ooalign{%
$#1\m@th\bigcirc$\cr
\hidewidth$#1\m@th\wedge$\hidewidth\cr
}%
}%
}
\makeatother
\begin{document}
$h \owedge k_{h \owedge k_{h \owedge k}}$
\end{document}
