My problem involes a qed symbol which appears too early.
My observations are that it happens after a displaymath inside an item of an unboxed inline list.
All of this seems to be necessary to produce the error.
The packages involved are ntheorem
, thmtools
and enumitem
.
If I compile this code with lualatex
using TeXLive 2011
.
\documentclass{scrreprt}
\PassOptionsToPackage{thmmarks}{ntheorem}
\PassOptionsToPackage{inline}{enumitem}
\usepackage{amsmath,MnSymbol}
\usepackage{ntheorem,thmtools}
\usepackage{
enumitem,
}
\declaretheoremstyle[qed={\quad\blacksquare}]{plain}
\declaretheorem[style=plain,numbered=no,name=Proof]{proof}%
\begin{document}
\begin{proof}
\begin{enumerate*}[mode=unboxed]
\[a\]
Still proof.
\end{enumerate*}
\end{proof}
\end{document}
the output becomes:
The symbol is placed correctly if the enumerate*
environment isn't used or if $$
or \begin{displaymath
and \end{displaymath}
is used to mark displaymath mode instead of \[
and \]
.
Clearly, the qed symbol should be at the end of the proof after “Still proof.” – What am I doing wrong? Couldn't find anything so far.

As per my earlier comment
ntheorem
seems to add the\qed
to the very last display mode equation. So a hack is to to end a proof withCode:
