Thank you very much for your tip!

Sure, you're welcome. Please keep auctex-devel@gnu.org in CC and use
Reply-To-All in your MUA, otherwise your messages won't be visible on
the list. Thanks.

But what about this example:

\documentclass[a4paper,11pt]{article}

\usepackage{babel}
\usepackage{amsmath}

\begin{document}

\[
\begin{vmatrix}
   \hfill\frac1{3}-\lambda& -\frac14\\[2pt]
   -\frac14& \hfill\frac1{3}-\lambda
\end{vmatrix}
=\bigg(\frac13-\lambda\bigg)^2-\frac1{16}=0\iff
   \frac13-\lambda=\pm\frac14\iff\lambda=
     \begin{cases}
       \frac13-\frac14=\frac1{12}\\[3pt]
       \frac13+\frac14=\frac7{12}\,.
     \end{cases}
   \]

\end{document}

Which version of AUCTeX are you using? That reminds me of a shortcoming
which was fixed last April with commit fa547aa71e[1]. Can you please
update your AUCTeX installation and try it again? Your example indents
fine for me if I paste it into a .tex file, mark it and hit
'M-x indent-region RET'.

Best, Arash
