I just posed a question in causal set notation (in general relativity), referencing papers 50 years old and 5 years old, seeking to know whether notation has changed or usage is a matter of personal preference.
This question has been put on hold as being "primarily opinion-based".
However, what I want to know is the fact of whether it is a matter of opinion or whether there is some authority or consensus for one form or another; I am writing a paper intended for submission and need to be correct in my notation if I am to avoid avoidable referee objections.
I also can't see how to discuss this with the admin who put it on hold.
How are such questions to be managed when, as in this case, the asker acknowledges that the answer may involve discussion of matters of opinion but is not seeking opinions about opinions (if they are such) but facts about them.
(Getting rather more meta than I would like, but I can't see how to avoid it!)
Question is here
