When it comes to numbering results in a mathematical publication, I'm aware of two methods:



  1. Joint numbering: Thm. 1, Prop. 2, Thm. 3, Lem. 4, etc.


  2. Separate numbering: Thm. 1, Prop. 1, Thm. 2, Lem. 1, etc.


Every piece of writting advice I have encountered advocates the use of 1. over 2., the rationale being that it makes it easier to find the result based on the number. It seems that 1. is more popular than 2., although 2. still exists, especially in books. I can only imagine that people using 2. must have a reason, but I have not yet to encounter one. I hope it is not too opinion-based to ask:



What is the rationale for separately numbering theorems, propositions and lemmas, like in 2.?"

    If a short paper has three main results, the second of which has a long proof with five lemmas, then Thm. 1, Thm. 2, Lem. 1-5, Thm. 3 makes total sense.

    I have always assumed that most people using method 2 haven't really thought about it and are just letting LaTeX get away with its default behavior. To make LaTeX use method 1 you have to explicitly tell it to use the same counter for all results.

If the paper contains three main theorems, each generalizing the previous, it is nice to be able to discuss them like this:




While the extension of Theorem 1 to Theorem 2 uses only complex analysis, in Theorem 3 we will have to employ some Ramsey theory.
