What is the meaning of the expression "note added in proof"?
Could it be used like a "post scriptum (PS)", or just to writte some new information about a subject? And what does "in proof" mean exactly in this context?
The context is the following: I have been reading this expression here and there in many different contexts. I have always thought I understood it, its meaning seemed to be self evident, so I never bothered thinking deeper about it. Now when I try to use it myself (for example in UsingEnglish forum's posts), I see I do not understand it exactly.
But I think I can uderstand it now, I used to think "in proof" should really provide a "proof to an argument", but I see from your answer "at proof stage" may be also understood, that is. a note added while the text was being "proof read". In this second meaning shouldn't it read "note added at proof (stage)" rather?
Maybe this expression was first used only with the first meaning and then it was trivialized to mean also the second?
Possible, but I really think the context would provide the answer.
If I understand right it, there are two distinct meanings to this expression:
1 - a note added at proof stage (for example an erratum)
2 - a note added to prove an argument (for example a mathematical demonstration)
Both are correct and the context identifies the current meaning.
Is that so?
That is how I see it
