@Peter Closed questions with a negative score and no answers are deleted automatically after some time.

@MartinR In the meantime, the question can be bountied, we cannot afford to wait so long.

@Peter You can not start a bounty on a closed question.

OK

How could this post get such a score ?

@Peter Interestingly, it did not get on the HNQ but rather went viral for a brief time on Twitter and possibly other media.

@TheSimpliFire Another case of "nonsense attracts tons of people" , it seems.

Opinions about this one.

@NikhilKumarSingh Is this procedure even valid ? As far as I know, we cannot apply power rules for complex numbers.

@Peter I think that it is a non-answer.

If it actually is correct, it is a good answer since we just have to set $w=\pi$ in the given expression to get a real number as desired. But I am not sure whether the "s" actually vanishes as demonstrated.

@Saad This user appeared before as well today (ref rschweib's comment), and the questions they are posting remind me vaguely of a graduate admission exam, though it could very well be from an old exam. I don't think of flagging, but we should watch this.
I think I've erred here, but this question actually looks okay to me. So the source is "instructor gave us this problem" and the background is "we haven't learnt non-linear recurrences in class". I've mistakenly voted to delete, I think this could stay maybe.

@Saad The answer is not helpful, if correct at all.
@TeresaLisbon borderline. I decided not to delete-vote, but I well could understand if somebody else would do.

@Peter Ok, but if it does happen then I'd like discussion on this, so I'll put it in the reopen thread. I value the answer, because I don't think I've seen a log transformation on recurrences that often.

After serially downvoting my posts in the last few days, some user is trying to close questions I've answered: math.stackexchange.com/review/close/1640244

12:52 PM
@TeresaLisbon If you want to have this closed, why did you then post a comment with "sufficient context" ?

@Peter Improved.
(I might be lowering standards, but I think that "homework exercise" statement tells me that they don't know what is going on, and they tried their best with respect to reading that page and editing the question). If it still feels close worthy, I'll remove the comment and you can close the question.

@Saad Do you think it is the same user ?

Shall we undelete this post because of the given answer followed by a self-deletion ?

@Peter Undeleting it to close and delete it seems counterintuitive. The question is a bare bones PSQ, and should not have been answered in the first place.

@amWhy makes sense. Additionally, it had not received upvotes at the time of the deletion.

@Peter I can see both arguments: a user should not delete a post immediately after getting a post; a PSQ should be closed, not answered, and ultimately deleted.

@amWhy Therefore my question , but I think we just should leave it deleted.

@Peter Indeed.

Moreover : It is strange to assume that all primes are Mersenne primes, but this is another story.

@Peter I understand. The question is legit.
@Peter Indeed. Why would we want to say Mersenne primes, rather than primes, (if they are equivalent!)

Hola, @quid!

Hello. I'll leave near instantly though.

No problem. That was supposed to be wide open eyes and open mouth, from left to right!

Consider closing. The OP posts an image of the problem, and merely writes two PSQ questions for someone else to answer for them.
@Peter When you star as often as you do, nothing gets noticed. We don't all need to know what "Peter" thinks, given that most stars in this chat come from you. Please, keep stars for earmarking posts that might be useful in the next couple of days. You can create a chatroom, or a blog, to record your "likes" and dislikes, and why's.

C Peer review of proof? of Riemann Hypothesis.

@ArcticChar Yikes! Now their question has become: Can you prove formula 7 (or 9) for me? Thanks for posting here.
@ArcticChar and others in CURED: How can this have received 4 downvotes, and only one close vote?? I am referring to the question linked by @ArcticChar.

Please close this questionIt seems OP is doing some work in the comments, but the post is low quality as it stands.
