有人能帮助我如何在 Latex 中构建这个链吗？

使用tikz-cd：
\documentclass{article}
\usepackage{tikz-cd}
\begin{document}
\begin{tikzcd}[cells={nodes={minimum height=2em}}]
0\arrow[r] & \frac{E}{\phi} \arrow[r,"\delta"] \arrow[d] & H^{1} \arrow[r,"\rho"]\arrow[rd,"\bar{\rho}"] \arrow[d,"Res"] & H^{1} \arrow[r]\arrow[d,"Res"] & 0\\
0 \arrow[r] & \Pi\frac{E}{\phi} \arrow[r,"\rho_{\nu}"] & \Pi_{\nu}H^{1} \arrow[r] & \Pi_{\nu}H^{1} \arrow[r] & 0
\end{tikzcd}
\end{document}
自己输入剩余的符号。:)
