将箭头改为$\mapsto.$

Question

我想将下图中的箭头改为$\mapsto$：

\begin{center}
\begin{tikzcd}[arrows=<-]
  & s'_1 \ar[rd,"j_1^*"]\\
  s \ar[ru,"i_1^*"] \ar{r}{i_2^*} \ar[rd,"i_3^*"'] & s'_2 \ar[r,"j_2^*"] & s'\\
  & s'_3 \ar[ru,"j_3^*"']
\end{tikzcd}
\end{center}

任何帮助将不胜感激！

Answer 1

非常简单：

\documentclass{article}

\usepackage{tikz-cd}

\begin{document}

\begin{center}
\begin{tikzcd}[arrows={<-|}]
  & s'_1 \arrow[rd,"j_1^*"]\\
  s \ar[ru,"i_1^*"] \ar{r}{i_2^*} \ar[rd,"i_3^*"'] & s'_2 \ar[r,"j_2^*"] & s'\\
  & s'_3 \ar[ru,"j_3^*"']
\end{tikzcd}
\end{center}

\end{document} 

Answer 2

像这样？

\documentclass{article}
\usepackage{tikz-cd}
\begin{document}
\begin{center}
\begin{tikzcd}[arrows=mapsfrom]
  & s'_1 \ar[rd,"j_1^*"]\\
  s \ar[ru,"i_1^*"] \ar{r}{i_2^*} \ar[rd,"i_3^*"'] & s'_2 \ar[r,"j_2^*"] & s'\\
  & s'_3 \ar[ru,"j_3^*"']
\end{tikzcd}
\end{center}
\end{document}
