### ntheorem and the list of theorems

Hello,

I'm trying to use the package ntheorem. I want display the list of the theorem.

\documentclass{article}

\usepackage[utf8]{inputenc}
\usepackage[english]{babel}

\usepackage[standard,thref,hyperref]{ntheorem}
\usepackage{thmtools}

\renewcommand*{\listtheoremname}{Liste des théorèmes}

\begin{document}

\section{Introduction}

\begin{theorem}
Let $f$ be a function whose derivative exists in every point, then $f$ is
a continuous function.
\end{theorem}

\begin{theorem}[Pythagorean theorem]
This is a theorema about right triangles and can be summarised in the next
equation $x^2 + y^2 = z^2$
\end{theorem}

\begin{corollary}
There's no right rectangle whose sides measure 3cm, 4cm, and 6cm.
\end{corollary}

\listtheoremname
\theoremlisttype{allname}
\listtheorems{all}

\end{document}

I obtain juste a simple line as list of theorem :

Liste des théorèmes theoremTheorem2Pythagorean theorem1 lemmaLemma11

I'm looking for how to obtain a real list of theorem.
Thank you.

### ntheorem and the list of theorems

please load hyperref package and replace \listtheorems{all} with \listtheorems{corollary,theorem}. Compile few times.

### ntheorem and the list of theorems

Hi deimi,

welcome to the forum!

Indeed, ntheorem doesn't load hyperref implicitly even though the option hyperref was used. Very good catch! I didn't notice that. Indeed it then compiles fine.

Instead of just outputting \listtheoremname, using a \section command would be good, to have a proper heading.
