The purpose of this thread is to help focus the attention of the community on posts that may require exceptional handling. This includes requests for reopen and undeletion votes. A request should be posted as an answer below.

Please do not use this thread to engage in debates on contentious matters (e.g. reasons for closure). That should be done in a separate linked thread. The goal is to keep this meta thread free of tension, so that everyone feels comfortable posting here. Please be polite, and respect the many different viewpoints in our diverse community.

To inform readers of the current (and past) states of the targeted post, please append tags such [REOPENED,RECLOSED] or [UNDELETED] at the start of the answer.

Beware that "short" requests such as "request reopening of <link>" may be automatically converted to comments by the SE software, so you may need to write more (e.g. why you think that the question should be reopened or undeleted).

  • $\begingroup$ For reopen requests that are run-of-the-mill (e.g. aren't meant to debate reasons for closure), do you think it would make sense to have a generic reopen-request thread, so that we don't end up with hundreds or thousands of questions on such. Then each request would simply be an answer in the reopen thread, and it being bumped would get the same exposure as a new question. Thoughts? Unless I hear any objections I will create such a thread. $\endgroup$ Oct 24, 2012 at 17:11

    $\begingroup$ @Willie: I think that we should delete old reopening requests and perhaps have one post/additional thread for indexing them. I should also think that any request older than $n$ days for some reasonable $n$ should be deleted.

    $\begingroup$ @Willie It's probably useful to have some nontrivial history remain so that folks $\rm < 10K$ can gain some idea about what types of questions do get reopened, and what types don't. By quickly scanning the requests it might help to convey some idea of the community consensus on marginal topics. To keep the unopened requests at the top of the active sort, they could easily be bumped if there is still interest. $\endgroup$ Dec 1, 2012 at 1:44

This question was closed. It seems to have been edited in the meantime, and seems reasonable to me at this point.

I gave a partial answer in a comment, but it would be more convenient for everyone if it could be reopened and answered properly (with hints, further explanation, whatever people find appropriate).

[REOPENED]

In my relatively expert opinion this question is perfectly clear. Yet it was put on hold as unclear what you are asking. The OP also has put a rather non-trivial amount of effort into understanding the question given that they say to have implemented the usual Viterbi decoding algorithm. Admittedly the OP has built a bit of a history in asking coding theoretical questions that actually are unclear and/or show very little effort. This question is not one of those. I will answer it in a comment (it has a very quick answer), and let anyone else take a first bite at answering. But keeping this on hold sends IMHO a wrong signal.

Ambiguity in the Natural Numbers asks what seems to me to be a very clear and specific question about whether two different axiomatizations of the natural numbers can contradict one another. This has been a serious research subject in the past, and it admits a positive answer, which Henning Makholm and I independently wrote.

It was closed as "unclear", but I disagree.

Counting Shaded Squares was closed as "missing context or other details". It is a perfectly clear and straightforward question about combinatorics: how many ways are there to color exactly two squares in an $n×n$ array. Marko Riedel and I each had no trouble answering it.

(I voted to close, not as "missing context" but as a duplicate of how many unique patterns exist for a NxN grid . But on review I see that the two questions are different.)

Becoming Better at Math was closed on the grounds of being primarily opinion-based. It is community wiki with and tags. Though there are many possible answers (hence the CW), I do not find the question to be opinion based, as it is a call for guidance from experienced mathematics students, who in general do not disagree about most fundamental aspects of learning mathematics. (In other words, though opinion-based answers to this questions may exist, certainly not all answers are opinion-based.) This question could serve as a useful collection of practical advice specifically aimed at high school aged students preparing to major in math in college.

I believe that this question should be reopened. It is asking why $i\times 0=0$, but has been closed as "unclear what you are asking". I do not see why this is unclear: it is very clear!

The meta question is whether it is better to close such a question or to allow people to provide answers either explaining the impossibility or exploring the extent to which the use of geometry can be reduced or eliminated. My own view is that there are many different ways to define the sine function; in some definitions, no geometry is needed to prove the statement, even though that definition might have a geometric interpretation or inspiration. $\endgroup$ Feb 3, 2014 at 11:56

I gave a hint, then started typing in my welcoming speech, explaining what was problematic about the question. After the first such comment, the OP thanked for the comments, deleted the question and the account. I was like "WTF?". I'm sure we've all seen worse. Many of them won't post that thank you comment :-/ $\endgroup$ Dec 2, 2014 at 7:51

[(DELETED, UNDELETED)^2, DELETED]

https://math.stackexchange.com/questions/1022883/let-xn-be-a-bounded-but-not-convergent-sequence-prove-that-xn-has-two-subse was recently deleted.

The original question suffered from a lack of context. The poster supplied context before the question was closed (unfortunately, in the form of an answer, rather than as an edit), but the final vote(s) to close were cast anyway. Then people started voting down the (good) answers that had been posted, presumably to make it easier to delete the question, so the content of the answers is gone now, as well.

I'd like to see the question undeleted.

I'd also like to see people stop voting down good answers, but it seems that is asking for too much.

    $\begingroup$ Voted to reopen the current version. I didn't downvote those answers, but if they arrived when the question was very bad I understand the reason. That is the only way to try and pass the message. $\endgroup$ Dec 1, 2014 at 17:07

    $\begingroup$ If it is opened it can be linked to a couple of duplicates provided in the comments. $\endgroup$ Dec 1, 2014 at 17:12
  • $\begingroup$ Oops! I had missed those. Thanks for pointing them out, @Jonas. Can close it as a dup instead :-/ $\endgroup$ Dec 1, 2014 at 18:10

    $\begingroup$ I've just cast the final vote for undeletion; it's better to leave duplicates undeleted (yet linked) for searching. $\endgroup$

    $\begingroup$ @Najib, there are four answers to that question, but three of them were subject to downvoting attacks and deleted. Would you be OK with keeping the question undeleted, if the three deleted answers were undeleted as well? $\endgroup$ Dec 24, 2014 at 20:13

    $\begingroup$ There are already two questions, one of them with the exact same text for the question (so the "google" argument doesn't hold). The other questions already mention Bolzano-Weierstrass in the question text. They both have upvoted, undeleted answers. Meanwhile this question only had one undeleted answer, heavily downvoted. If it's undeleted it should be closed as a dup anyway. What do you want, exactly? Or better, why do you want this question undeleted so bad? $\endgroup$ Dec 25, 2014 at 9:14

    $\begingroup$ What I want is for the question to be undeleted, reopened, closed as a duplicate, and its answers undeleted and merged into the other question, with the malicious downvotes reversed, and the malicious downvoters suspended. That's not asking much, is it? $\endgroup$ Dec 25, 2014 at 17:40

    $\begingroup$ The first part of your request seems reasonable; the reversion of the down-votes, however, not so much, and the request for suspension is definitely not reasonable. $\endgroup$

[Undeleted]

Consider undeleting this question for the reason that the OP deleted out of frustration (check the comments) and it's a perfectly good question with the exception of the missing quantifiers, but this is something which the OP is lacking in knowledge and can easily be addressed.

    $\begingroup$ @Jonas Um, in this case I guess maybe a serial downvoter? And indeed, some serial downvoting was reversed today. $\endgroup$ Dec 27, 2014 at 9:12

[REOPENED] I would like to see

Properties of the number 50

reopens.

With $13$ upvotes it is clear that there are members of th comunity that find it to be interesting, and I recall such a question here (that asked for integrals and etc' with the value being someones age was not closed).

$\endgroup$

    $\begingroup$ Compare the two questions though: Answers to "integrals that evaluate to 59" are interesting maths puzzles. Answers to "what's interesting about 50" are trivia (to illustrate, the top-ranked answer at the moment is on Wikipedia). $\endgroup$ Oct 31, 2012 at 10:21

    $\begingroup$ I definitely think that such questions should be closed. By leaving it open, you are setting a standard which allows for any such question with $50$ replaced by any other number. It is too localized. Think of the extreme case. I would not want $200$ different questions on this site each regarding what is interesting about some different integer. There is no mathematical content there. Upvotes do not constitute a valid reason for reopening. One of the more upvoted threads on MO is about jokes, which is off topic despite being voted up. $\endgroup$ Nov 15, 2012 at 15:39

[REOPENED] I would like Covariant derivative on hypersurface in $\mathbb{R}^n$ reopened. It was closed as duplicate but I don't think the answer in the question it's supposedly a duplicate of answers all of the interesting questions the OP has raised.
