Use 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}

Type the remaining symbols yourself. :)

  • Thank you for the quick response! I have tried this code but it gives me errors. Is there anything I can do? – P.D. Aug 30 '15 at 2:42
  • @P.D. May be you have old tex distro. Try updating it so that you have recent packages. – user11232 Aug 30 '15 at 2:43
