Unable to get Weierstrass p symbol in latex

Question

I am trying to write the symbol $\wp$ in springer template, but I am getting output 'wp' instead of the symbol (amssymb and amsmath are also installed). Can anyone please help!

Here is a MWE

\documentclass[sn-mathphys]{sn-jnl}
\usepackage[utf8]{inputenc}

\title{springer trial}
\author{ }
\date{}

\begin{document}

\maketitle

\section{Introduction}
The symbol $\wp$ is not there.
\end{document}

In logs and output files, I am getting

Package breakurl Warning: You are using breakurl while processing via pdflatex.(breakurl) \burl will be just a synonym of \url. on input line 48.

But I don't think the output error has anything to do with the symbol. It's there even after I remove the symbol code.

Answer 1

For some (unknown) reasons, the package loads the program package, that offers almost nothing useful, in my opinion.

This package does

%% require the {...} for \wp and \WP
\let\oldwp=\wp % save old \wp (curly p character)
%\def\wp#{\@wp}
%\def\@wp#1{\mbox{\normalshape wp}(#1)}
%\def\WP#{\@WP}
%\def\@WP#1{\mbox{\normalshape WP}(#1)}
%% Don't require {...}, ie use normal parentheses where required:
\def\wp{\mbox{\normalshape wp}}
\def\WP{\mbox{\normalshape WP}}

What such a (disputable as regards to code) redefinition of \wp is useful for, I don't know.

Anyway, you can use \oldwp instead.
