对于这种简单的情况,您也可以通过简单的命令构建符号来重现图表。有许多带有箭头符号的软件包,例如MnSymbol
。
这是您示例中符号的构造。导入单个符号的代码MnSymbol
基于 Ulrike Fischer 的回答这里。
\documentclass{article}
\usepackage{mathtools}
\DeclareFontFamily{U}{MnSymbolA}{}
\DeclareFontShape{U}{MnSymbolA}{m}{n}{
<-6> MnSymbolA5
<6-7> MnSymbolA6
<7-8> MnSymbolA7
<8-9> MnSymbolA8
<9-10> MnSymbolA9
<10-12> MnSymbolA10
<12-> MnSymbolA12}{}
\DeclareSymbolFont{MnSyA} {U} {MnSymbolA}{m}{n}
\DeclareMathSymbol{\lcurvearrowdown}{\mathrel}{MnSyA}{187}
\DeclareMathSymbol{\rcurvearrowdown}{\mathrel}{MnSyA}{195}
\newcommand*{\arrowsdots}{%
\rcurvearrowdown\mkern1mu%
\mathclap{\raisebox{-.65\height}{\(\cdot\)}}%
\mathclap{\raisebox{ .4\height}{\(\cdot\)}}%
\mkern1mu\lcurvearrowdown%
}
\begin{document}
\( \mathrm{Set}^{\arrowsdots} \)
\end{document}

答案3
像这样吗?
\documentclass{standalone}
\usepackage{tikz}
%Resize to relative size (em)
%Put the TikZ picture inside a box, just in case
\newcommand{\love}{\resizebox{0.5em}{!}{\hbox{\tikz\draw[fill=red] (0,0) rectangle (1,1);}}}
\begin{document}
$4^{\love}$
\begin{Large}
$4^{\love}$
\end{Large}
\begin{Huge}
$4^{\love}$
\end{Huge}
\end{document}
要真正回答这个问题,有点像尝试。如果你对 TikZ 足够了解,你可以尝试使用箭头和点大小。
\documentclass{standalone}
\usepackage{tikz}
\usepackage{amsmath}
\usetikzlibrary{arrows,positioning}
\newcommand{\nicepicture}{%
\begin{tikzpicture}
\node[circle, fill=black,inner sep=0pt,minimum size=.075em] (A) at (0,0){};
\node[circle, fill=black,inner sep=0pt,minimum size=.075em] (B) at (0,.3){};
\draw[->] (B.west) to [bend right=45] (A.west);
\draw[->] (B.east) to [bend left=45] (A.east);
\end{tikzpicture}
}
\newcommand{\myarrows}{\resizebox{!}{.5em}{\hbox{\nicepicture}}}
\begin{document}
$\text{Set}^{\myarrows}$
\begin{Large}
$\text{Set}^{\myarrows}$
\end{Large}
\begin{Huge}
$\text{Set}^{\myarrows}$
\end{Huge}
\end{document}
