# Title of the theorem

in my paper the text inside theorem is italic while the word Theorem 1 is bold and not italic. I would like to have a title of the theorem also not italic. The example is here:

Theorem 1. (The title) Let the set...

How can I do it? I tried to type \begin{theorem}{title here} but it doesn't work.

Usually

\begin{theorem}[The title]
Some statement
\end{theorem}


should do what you want. The standard LaTeX setting prints in boldface also the title, which doesn't happen when amsthm is loaded.

Thanks, it works. –  Ilya Jul 3 '11 at 19:39
@Gortaur: with default settings also the title would be bold. –  Stefan Kottwitz Jul 3 '11 at 19:46
@Stefan Not with amsthm, which I prefer. –  egreg Jul 3 '11 at 19:58
@egreg: I prefer it too. It just hasn't been mentioned in the question, so I tested without. –  Stefan Kottwitz Jul 3 '11 at 20:12
You might like to test  \newtheorem{theorem}{\textit{Theorem}} before \begin{document} then  \begin{theorem} Some statement \end{theorem}
