[Tex/LaTex] How to rename theorem (or lemma) in Beamer

beamertheorems

I usually write theorem as follows:

\begin{theorem}[abc]
...
\end{theorem}

Then the title will be Theorem (abc). I would like to name it differently, for instance, "Theorem of abc", "ABC theorem"… Could anyone tell me how to do it?

Thank you very much!

Best Answer

You can redefine the theorem begin, and theorem end templates. In the following example, I suppressed the numbering and the parentheses, and added "of" between the theorem name and the theorem additional note:

\documentclass{beamer}

\makeatletter
\setbeamertemplate{theorem begin}
{%
\begin{\inserttheoremblockenv}
{%
\inserttheoremheadfont
\inserttheoremname
\ifx\inserttheoremaddition\@empty\else\ of\ \inserttheoremaddition\fi%
\inserttheorempunctuation
}%
}
\setbeamertemplate{theorem end}{\end{\inserttheoremblockenv}}
\makeatother

\begin{document}

\begin{frame}
\begin{theorem}[Fermat]
Test theorem.
\end{theorem}
\end{frame}

\end{document}
