Issue with diagrams made using tikzcd

Question

I have made the following diagrams using the tikz-cd environment:

1. \[\begin{tikzcd}[column sep=25pt]\emph{Aut}(A)\arrow[rr,"\phi_h"]&&\emph{Aut (A')\\&G\arrow[ur,"\rho'"]\arrow[ul,"\rho"]\end{tikzcd}\]

2. \[\begin{tikzcd}[column sep=25pt]X\arrow[rr,"h"]\arrow[dr,"f"]&&Y\arrow[dl,"g"]\\&A\end{tikzcd}\]

How can I make it so that the $\rho'$ in the first diagram and the $f$ go below the arrow? Any help is appreciated.

Answer 1

Use ' after "..." to move it to the other side if the arrow

\documentclass[a4paper]{article}
\usepackage{amsmath}
\usepackage{tikz-cd}
\DeclareMathOperator\Aut{Aut}
\begin{document}
\[
\begin{tikzcd}[column sep=25pt]
  \Aut(A)\arrow[rr,"\phi_h"]
  && \Aut (A')
    \\
    &G\arrow[ur,"\rho'"']\arrow[ul,"\rho"]
\end{tikzcd}
\]
\[
\begin{tikzcd}[column sep=25pt]
  X\arrow[rr,"h"]\arrow[dr,"f"']
  &&
  Y\arrow[dl,"g"]
  \\
  &
  A
\end{tikzcd}
\]
\end{document}
