A: Why was "The origin(s) of the word “elliptic” migrated to hsm?

History of Science and Mathematics moderator here. We've talked it over and have just sent the question back to Math Overflow (I closed it as off-topic on HSM, so that should bounce it back to MO automatically). Over the last six years, we've had a lot of conversations with other STEM sites abou...

Q: The origin(s) of the word "elliptic"

The word elliptic appears quite often in mathematics; I will list a few occurrences below. For some of these, it is clear to me how they are related; for instance, elliptic functions (named after ellipses, see here) are the functions on elliptic curves over $\mathbb C$. For others, I do not know ...

I suppose that the intention of the moderators from History of Science and Mathematics was to give the question back and then reopen it. I voted to reopen and the question is now in the review queue.

The fact that the question was migrated back and then it stayed closed suggests that very likely there wasn't much communication about this between the moderators of the two sites. After all, so far the only activity by a MO moderator in the meta thread was one comment.

But maybe I am missing something and this was intentional? (So the plan was to get question back to MO and leave it closed? Perhaps to let the MO community evaluate whether the question is on-topic on MO or not...?)

@MartinSleziak my assumption was that when migrated, it was "closed and migrated", and that all moderators could do at HSE was to cancel migration, so that it naturally came back to MO as closed

Martin Sleziak

Now the questions was reopened: revision history, timeline, review.

YCor

@MartinSleziak sure; I actually commented this at the meta-MO post

Martin Sleziak

@YCor Yes, but MO mods could have reopened it. (And I assume they would do so if they acted in coordination with the HSM mods.)

it worked, the question is back on MO --- mathoverflow.net/questions/359705/… — Carlo Beenakker 2 hours ago

@CarloBeenakker thanks for the info! Now it's back on MO I get more info about the timeline. On May 13 it was closed-migrated (by 4 votes, the 4th being by a moderator). Today (11h ago) the migration was rejected (the technical way to HSM to give it back to MO, possibly after flags as suggested here). Then if I understand correctly, the question came back to MO as a closed question. 7h-1h ago it was reviewed with 2 votes to reopen, and 1 to leave closed. Then it was reopened based on 5 votes. (Looks like it was reopened twice consecutively, I'm not sure what happened.) — YCor 32 mins ago

I don't really get what you mean by saying that it was "reopened twice".

YCor

@MartinSleziak But the migration was technically "refused", which means an action by the HSE mods. Possibly in coordination with MO mods. Possibly MO mods had no objection, but considered that it's up to the community to reopen it (and I'd agree).

Martin Sleziak

Yes, that much is clear.

It is also clear that MO mods are rather secretive and do not like to talk to MO users. This MathOverflow site seem to be quite clandestine organization. :-)

This seems to be related to the above question too - however, this user has already posted on MathOverflow Meta.

Wow, such a response! But shouldn't have said HSM would never be able to leave the Beta stage. In fact, they should encourage posting such questions here to increase the traffic and make it a busy site as well.

@YCor If by "reopened twice consecutively" you meant that the timeline has two entries called "reopen" and "reopened"; one of them is a link to the review, the other one is actual reopening.

YCor

@MartinSleziak If I see the timeline it's written that it was first (a) "reopen completed" (2 reopen votes vs 1 leave closed vote) and then that it was (b) "reopened" with 5 votes. At first sight (a) looks like leading to reopening, but apparently not since it was followed by reopening. So I'm not sure what's the technical role of (a).

Martin Sleziak

"reopen completed" has a link to the review: mathoverflow.net/review/reopen/132280

Users can vote to reopen also outside of the review. This item in the timeline contains link to the review in the reopen votes review queue.

YCor

@MartinSleziak OK, but do you understand what is the role of the review then?

Martin Sleziak

Similarly you can see close review linked in the entry which says "close completed" ans has link to: mathoverflow.net/review/close/131239 And it was later closed.

@YCor The role of close/reopen review queues is that they make recent close/reopen votes visible in one place and available to users for reviewing.

If the posts go into the review queue, they are less likely to go unnoticed. (At least on sites where users actually try to help with the site moderation. I am not sure to which extent MO users take part in review queues.)

YCor

@MartinSleziak OK, so the first vote led to the question to be added to the "reopen" queue (while, if the first vote had led to "leave closed", it would just have been left— while still possible to vote to reopen the question, but without advertisement on the review queue)

@MartinSleziak OK thanks, this seems to confirm my last deduction.

Martin Sleziak

I don't really get what you mean by: if the first vote had led to "leave closed".

If a closed post gets edited (within the time restriction, I think 5 days after closure), it goes into the review queue.

If a closed post gets a reopen vote, it goes into the review queue.

Meta Stack Exchange: What are the review queues, and how do they work?

Re: Now it's back on MO I get more info about the timeline. I suppose that as 10k+ user you should be able to see the timeline and revision history also for a post which was migrated away from MO.

I just check on my post - which was migrated to MO - that I can see the revision history and timeline on Mathematics. (I have 10k+ on that site.)

YCor

15:15

@MartinSleziak From the timeline, I can see an item called "reopen completed", with 2 votes "reopen" vs 1 vote "leave closed". So I mean: if this vote had, instead, led to a majority of "leave closed" votes.

YCor

15:34

@MartinSleziak I see. Probably I need the link to the original MO post to do so (which leads to the post on MO saying it was migrated)— which in this case does not longer exist. Was there a deterministic way to get this MO original from the HSE post? (Sorry for being so vague, I strongly feel that English is not my mother tongue when having such technical discussions...)

Martin Sleziak

@YCor To use the example from Mathematics - if I go to this post on MO: Characterization of Fréchet-Urysohn spaces using sequential continuity at a point

If I check either timeline or revision history.

I see there "Post Migrated Here from" and there I can click on a link which takes me here: math.stackexchange.com/questions/444908/… (I don't think it will work for users who have below 10k on Mathematics.)

There I can get link to the timeline and to revisions.

You can check yourself with some post which was migrated from MO, like this one: math.stackexchange.com/questions/3692400/…

"This question was migrated from MathOverflow because it can be answered on Mathematics Stack Exchange. Migrated 6 days ago." If I click on the link in "Migrated", I get this: mathoverflow.net/posts/361405/revisions

In this case it is displayed to me, too. I can also see the post here: mathoverflow.net/questions/361405/… But eventually the migration stub will be deleted on MO - so it will no longer be available to me. (As I am below 10k.)

Regarding "leave closed" - yes, sufficient number of such votes would mean that the post would no longer be shown in the review queue.

> Finally, you can also choose Leave Open (or Leave Closed in the reopen queue). What does this last option do? If enough people vote to leave a question open or closed, the question is removed from the close/reopen queue (respectively) and immediately begins aging the existing close or reopen votes on the question (it does not clear them). It also dismisses any recommend closure flags as declined.

YCor

@MartinSleziak that's the problem: on HSE my rep is just 100 or 101, so I had only a very partial timeline, not including any information about the users who voted migration (and even the number of votes) and so on, and I don't think I got a link to the original MO post there.
