Theorem numbering: lemmas numbered within theorems
Version: 2.x, 3.x, 4.x, 5.x - Scientific WorkPlace & Scientific Word
In many documents, all of the theorem-like environments---theorems, corollaries, lemmas, etc.---use a common numbering scheme. That is, they are typeset in a single sequence, as in this series:
Theorem 1, Corollary 2, Lemma 3, Theorem 4, Lemma 5, etc.
You can create independent numbering of theorem environments so that each environment has its own numbering sequence, as in this series:
Theorem 1, Corollary 1, Lemma 1, Theorem 2, Lemma 2, etc.
You can also
The numbering scheme for theorem-like environments is controlled by \newtheorem statements, which are typically included in the document preamble.
You can create a numbering sequence in which one theorem-like environment is counted within another and the numbering is restarted with each new outer environment. The result might be a numbering scheme like this:
Theorem 1, Lemma 1, Lemma 2, Theorem 2, Lemma 1, Lemma 2, Theorem 3, Lemma 1, Lemma 2, etc.
You can create an alternate numbering scheme such as this:
Theorem 1, Lemma 1.1, Lemma 1.2, Theorem 2, Lemma 2.1, Lemma 2.2
