Multiple Commutative Diagrams

Question

I need to make two commutative diagrams (I am using the CD environment) in the same line (I mean not one above the other) can anyone give me an idea?

Answer 1

Just place them in the same equation(*) environment, perhaps separated by a space (\quad or \qquad):

\documentclass{article}

\usepackage{amsmath,amscd}

\begin{document}

\begin{equation*}
  \begin{CD}
    a @>>> b \\
    @VVV @AAA \\
    c @= d
  \end{CD}
  \qquad
  \begin{CD}
    x @>>\alpha> y \\
    @VV\kappa V @A\beta AA \\
    v @<\gamma<< w
  \end{CD}
\end{equation*}

\end{document}
