如何在 tikz-cd 环境中乳胶下图？

Question

我对 tikz-cd 交换图包还不太熟悉。如何在 tikz-cd 环境中将下图转换为乳胶图？ 提前致谢！

Answer 1

尝试自己绘制图表并在遇到困难时寻求帮助是一种很好的做法。否则你什么也学不到。

\documentclass{standalone}
\usepackage{tikz-cd}
\begin{document}
\begin{tikzcd}
 & & & H_n(X_{n+1},X_n) = 0 & \\
H_n(X_{n-1}) = 0 \ar[rd] & & H_n(X_{n+1})\cong H_n(X) \ar[ru] & & \\
 & H_n(X_n) \ar[ru,"i_n"] \ar[rd,"j_n"] & & & \\
H_n(X_{n+1},X_n) = 0 \ar[ru,"\partial_{n+1}"] \ar[rr,"d_{n+1}"] & & H_n(X_n,X_{n-1}) \ar[dr,"\partial_n"'] \ar[rr,"d_n"] & & H_{n-1}(X_{n-1},X_{n-2}) \\
 & & & H_{n-1}(X_{n-1}) \ar[ru,"j_{n-1}"'] & \\
 & & H_{n-1}(X_{n-2}) = 0 \ar[ru] & & \\
\end{tikzcd}
\end{document}
