Hello. I am writing a document using the "book" template and environments like theorems, propositions, lemmas and corollaries use diferent counters. I would like my document to share the same counter at those environments, so we would have:
Theorem 1
Proposition 2
Corollary 3
Lemma 4
instead of:
Theorem 1
Proposition 1
Corollary 1
Lemma 1
Is there any easy way to do so? My deadline is getting close and I really need this.
Thanks in advance,
Anderson Brasil
