答案1
该符号的stix
字体\intprod
对应于 U+2A3C,打印方式为 ⨼
无论如何,构建这样的几何形状并不是很困难。
\documentclass{article}
\usepackage{pict2e}
\makeatletter
\DeclareRobustCommand{\intprod}{%
\mathbin{\mathpalette\int@prod{(0.1,0)(0.9,0)(0.9,0.8)}}%
}
\DeclareRobustCommand{\intprodr}{%
\mathbin{\mathpalette\int@prod{(0.1,0.8)(0.1,0)(0.9,0)}}}
\newcommand{\int@prod}[2]{%
\begingroup
\sbox\z@{$\m@th#1+$}%
\setlength\unitlength{\wd\z@}%
\begin{picture}(1,1)
\roundcap
\polyline#2
\end{picture}%
\endgroup
}
\makeatother
\begin{document}
$v\intprod \omega=i_{v}\omega$
$v\intprodr \omega=\omega i_{v}$
$A_{v\intprod \omega}$
\end{document}
答案2
如果\lrcorner
太小,为什么不简单地调整其大小?
我已经使用过包装\scalebox
中的功能graphicx
。
\documentclass{article}
\usepackage{mathtools, amssymb}
\usepackage{graphicx}
\newcommand{\intprodl}{%
\mathbin{\scalebox{1.5}{$\lrcorner$}}%
}
\newcommand{\intprodr}{%
\mathbin{\scalebox{1.5}{$\llcorner$}}%
}
\begin{document}
$v\intprodl \omega=i_{v}\omega$
$v\intprodr \omega=\omega i_{v}$
$A_{v\intprodl \omega}$
$A_{v\intprodr \omega}$
\end{document}
