\section*{Recommendations for \LaTeX}
Don't use:
\begin{itemize}
\item \verb+$$...$$+ but \verb+\[...\]+ or \verb+\begin{equation}...\end{equation}+
\item \verb+$a \over b$+ but \verb+$\frac{a}{b}$+
\item \verb+{\cal ...}+ but \verb+\mathcal{...}+
\item \verb+{\bf ...}+ but \verb+\textbf{...}+
\item \verb+{\it ...}+ but \verb+\emph{...}+
\item \verb+\'e+ for instance to get an accent but type it directly (\verb+é+)
  using the UTF8 encoding.
\end{itemize}
More generally, it is worth having a look at documents that highlight obsolete
commands and
packages\autocite{ensenbach2016,ensenbach2011,trettin2007,ensenbach2011a,trettin2007a}.

\subsection{Theorems tests}
\begin{theorem}[Bolzano–Weierstrass]\label{thm-bolzano-weierstrass-\languagename}
  A subset of $\bbR^n$ ($n\in\bbN^*$) is sequentially compact if and only if it is
  closed and bounded.
\end{theorem}
\begin{proof}[not that easy!]
  ...
\end{proof}
\begin{definition}
  In Cartesian space $\bbR^n$ with the $p$-norm $L_p$, an open ball is the set
  \[
    B(r)=\set{x\in \bbR^n}[\sum _{i=1}^n\left|x_i\right|^p<r^p]
  \]
\end{definition}
\begin{remark}[Euler's identity]\label{rmk-euler-\languagename}
  One of the most beautiful mathematical equation:
  \begin{equation}
    \E[\I\pi]+1=0
  \end{equation}
\end{remark}
\begin{lemma*}[Zorn]
  Suppose a partially ordered set $P$ has the property that every chain has an
  upper bound in $P$. Then the set $P$ contains at least one maximal element.
\end{lemma*}
\begin{axiom}\label{my-axiom-\languagename}
  The following assertions are considered as true.
  \begin{assertions}
  \item\label{rare-expensive-\languagename} Anything that is scarce also is
    expensive.
  \item\label{cheap-horse-\languagename} A cheap horse is scarce.
  \end{assertions}
\end{axiom}
According to \vref{rare-expensive-\languagename,cheap-horse-\languagename}
from \vref{my-axiom-\languagename}, a cheap horse is expensive.
