I have a long (mathematical) document with parts, sections, subsections and paragraphs. The theorems etc. in the parts are numbered
Theorem 1.2.3
where the first number corresponds to the section
, the second number to the subsection
and the third to the number of the theorem, example, etc.
In the appendix (and only in the appendix), I will only use sections, no subsections. By default, a lemma in the appendix is numbered as
Lemma A.0.1
for the first lemma in the first appendix. I would like to suppress the subsection
number (only in the appendix), so that the first lemma in the first appendix is numbered as
Lemma A.1
I have tried to add \setcounter{secnumdepth}{1}
after the \appendix
command, but nothing changed.
Best Answer
If your lemmas use the
theorem
counter as in the MWE below, you can insert the linejust after the
\appendix
command. Note that you have to load the packagechngcntr
to be able to use\counterwithin
.MWE
Output
If your lemmas use a different counter, e.g.
lemma
, you have to change the mentioned line to, e.g.
