著者所属の上付き文字がタイトルに正しく表示されていない

Question

Elsevier の記事クラスを使用して所属の番号を正しく付けようとしていますが、イライラしています。

\begin{document}

\maketitle

\begin{linenumbers}
\begin{frontmatter}

\begin{abstract}
%% Text of abstract
Turnips go well with sausages.\\ 

\end{abstract}

\begin{keyword}
Turnips \sep More Turnips 
\end{keyword}

\end{frontmatter}
\end{linenumbers}
\end{document}

上付き文字が間違っています (ただし、少なくとも順序は正しいです)。さまざまなバリエーションを試しました。何かご意見はありますか?

Answer 1

番号付けは、使用しない場合は正常に戻るようです。\begin{frontmatter}...\end{frontmatter}
