| Jul 2, 2017 at 11:35 | comment | added | Maxis Jaisi | Dear @StefanKohl, thank you for your clarification. I guess I should point out that this question has nothing to do with the twin prime conjecture. I mentioned it because the modern way of writing the conjecture is to use lim inf, and I was curious as to when analytic number theorists first started using it, in connection with my question on the earliest uses of the concept. | |
| Jul 2, 2017 at 10:09 | comment | added | Stefan Kohl♦ | Arguably, commutative diagrams are a more advanced concept than lim sup and lim inf -- at least students are taught the latter in their first year of study, but the former usually only later. Also, mentioning a notorious open problem like the twin prime conjecture in a context like this typically accelerates closure of the question. Another aspect is that the two questions you refer to have been asked years ago, when MO was somewhat more welcoming to such questions. | |

| Jul 2, 2017 at 5:21 | comment | added | Maxis Jaisi | Dear @AlexandreEremenko, what is the difference between my question, and this mathoverflow.net/questions/59456/whence-commutative-diagrams and this mathoverflow.net/questions/194377/… ? | |
| Jul 1, 2017 at 15:17 | comment | added | Alexandre Eremenko | This is not an appropriate place to ask this question. You may try History of Science and Mathematics. I suppose that the first appearance of the upper limit is in Hadamard's formula for the radius of convergence, but I did not check this. | |
