I am using the xymatrix
command...
If I type the following code
\documentclass[11pt,oneside,a4paper,fleqn]{report}
\usepackage[all,cmtip]{xy}
\begin{document}
$\xymatrix{
0 \ar[r] & A \ar@{^{(}->}[r]& B \ar[r] \ar[d] & C \ar[d] \\ D \ar[r] & E \ar[r] & F \ar[r] \ar[ru] & G }$
\end{document}
everything works great...
The thing is, however, that I want to get rid of $D$ and $E$ in the lower row... i.e. I want to have two rows of exact sequences with only the box on the left... but if I just delete the section D \ar[r] & E \ar[r] &
, I get an error!
What should I do?
Thanks!
\documentclass{...}
and ending with\end{document}
