I have a document with a lot of lemmas and theorems. In the main part of the document there are sections and subsections, so I defined


to number the lemmas accordingly. But in the appendices I don't have subsections, so I figured it would be better if lemmas in the appendices are not numbered with respect to subsections, but with respect to sections. Therefore, I gave the command


just after opening the appendices with \appendix. But something strange happened. In appendix A I don't have lemmas. In appendix B the first lemma is numbered B.3. Could anyone explain me this behavior and suggest a solution?

Edit: If I give the command


the first lemma will be numbered B.1. But I'm still confused about why it is necessary to set the counter to 0.

Your counter resets at subsections not at sections, so

  • If I do this the number of the first lemma will be B.0.1.

  • I meant do that at the point that you rededine the counter, not at the satrt May 31, 2012 at 12:27
  • Ah sorry, I commented away \renewcommand\thelem... (which is silly, I admit). It works now, thanks!
