另一种选择是如何在 tikzcd 中仅在路口处过马路:
\documentclass{article}
\usepackage{tikz-cd}
\begin{document}
\begin{tikzcd}[column sep = large, row sep = large]
\ar[from=2-2]\gamma & \ar[from=2-1]\kappa\\
\null & \null
\end{tikzcd}
\end{document}
结果:
编辑: 与您的评论相关,我只添加了带有空格的解决方法。
\documentclass{article}
\usepackage{tikz-cd}
\begin{document}
\begin{tikzcd}[column sep = large, row sep = large]
\ar[from=2-2]\gamma & \ar[from=2-1]\kappa\\
\textcolor{white}{\gamma} & \textcolor{white}{\kappa}
\end{tikzcd}
\end{document}
