I want that theorems, lemmas, examples... are ended with a diamond. Like this:
I found out that I can use \hfill\mbox{$\diamond$}. But I already wrote my document with 100s of examples, lemmas... I don't want to set it manually. So I thought I could set it up in \theoremstyle. Where do I have to set this? Here's my MWE:
\documentclass[ngerman, fontsize=11pt, DIV=15, BCOR = 10mm,parskip=half-, twoside]{scrartcl}
\usepackage{babel}
\usepackage{amsmath}
\usepackage{amsthm}
\usepackage{amssymb}
\newtheoremstyle{definition}{}{}{}{}{\bfseries}{:}{5 pt}{}
\theoremstyle{definition}
\newtheorem{defi}[]{Definition}
\begin{document}
Here's the example.
\begin{defi}
Does the diamond appear?
\end{defi}
\end{document}
ntheorem
instead ogamsthm
then this is a feature of this package. Note that the method for styling inntheorem
is different.
