I'm using the thmbox package. I'm trying to find a way to make some of my theorems have the thmbox look, while having some other having the traditional theorems look.

My problem is that the different thmbox styles do not seem to include an "empty" style (to my knowledge, there's only the [S], [M] and [L] styles), and applying the \usepackage[nothm]{thmbox} makes all the theorems have the traditional theorem look.

  • Welcome to TeX.SX! Could you simply define the "empty" style using the regular \newtheorem command from amsthm? – Vincent Dec 23 '19 at 18:10
  • Unfortunately, no. The \theoremstyle option of asmthm only change the header in terms of font ans space. It doesn't seem to affect the use of thmbox style – ThmBoxingDay Dec 23 '19 at 18:24
  • It will indeed not affect thmbox if you define a theorem using \newtheorem. Just to be sure that I understand your question correctly, you want to have some theorems displayed in a thmbox style, and others in an "empty" style, like the one obtained by default using \newtheorem with amsthm? – Vincent Dec 23 '19 at 18:37
  • Yes! This is exactly what I would be looking for! – ThmBoxingDay Dec 23 '19 at 18:44

You can load the amsthm package before the thmbox package, and define a command \newemptytheorem from \newtheorem before \newtheorem gets redefined by thmbox.

\documentclass{article}
\usepackage{amsthm}
\let\newemptytheorem\newtheorem
\usepackage{thmbox}

\newemptytheorem{emptythm}{Theorem}
\newtheorem{boxedthm}[emptythm]{Theorem}

\begin{document}

\begin{emptythm}
A theorem in an "empty" style.
\end{emptythm}

\begin{boxedthm}
A theorem in a \textnormal{\texttt{thmbox}} style.
\end{boxedthm}

\end{document}
