How can I rename the theorem environment to proposition? In other words, I would like to print:

Proposition 1 instead of Theorem 1/Lemma 1, etc

Thanks in advance

PS: I am using koma-script article

  • Do you want to maintain your current code (which probably uses \begin{theorem} ... \end{theorem}), or create a new environment that prints Proposition instead of Theorem? Are you using any theorem-related packages?

  • I would like to create a new environment that prints Proposition. I am using amsmath package

  • @Yorgos -- amsmath has nothing to do with theorems. amsthm is the relevant package. Nov 28, 2015 at 21:20
