Math & Science ⇒ \newtheorem* already defined

[kunigami]

Hi,

I'm having trouble in using theorem without numbering. When I use:

Code: Select all

\newtheorem*{KL}{Klein's Lemma}

\begin{KL} Text text ... \end{KL}

I get the following error:

Command \* already defined. \newtheorem*{kl}

Is there a way to find out where the redundancy is, or how to work around this problem?

Thansk,

Apparently you're not using a document class or package that supports a starred version of \newtheorem.

Your example looks like it's right out of the amsthm package documentation, so why not just add:

\usepackage{amsthm}

to your document header?

If you have that added already, then probably some other package added afterwards is conflicting with it. Post a MWE if need be.

Weird, I think it was working without that before. But adding this package did the trick!

Thank you!
