I am using amsthm for theorems, propositions, and so on. But I altered the section numbering style so that it's '§1 First Section', hence my theorems are numbered (since I base them on sections) 'Proposition §1.1' or similar. How can I change this behaviour to just the numbers without '§', but also without having to change my sectioning style again?
\documentclass[a4paper,10pt]{scrreprt}
\usepackage{amsmath,amsthm}
\addtokomafont{sectioning}{\rmfamily}
\renewcommand{\thesection}{\S\arabic{section}}
\newtheorem{prop}{Proposition}[section]
\begin{document}
\chapter{Prerequisites}
\section{First Section}
\begin{prop}
Blub
\end{prop}
\end{document}
Thank you very much in advance!
