@TeresaLisbon the sad thing is that i would have stuff to say about that problem, would the person have put in any work

for instance, let $s=M^2 t/2$. Then (assuming $M>0$) the integral becomes $(2/M^2)\int_0^\infty e^{-(2/M^2)s} J_\nu(\sqrt{s})^2\,ds$

in which case I can recognize the integral as the Laplace transform of $J_\nu(\sqrt{s})^2$, evaluated at $p=2/M^2$

and then i can start trawling through Erdelyi to see if he has that Laplace transform

but if they're not going to put even a little bit of work of their own? nope

@Semiclassical Unfortunate, it happens sometimes. Consider self-answering if it goes, perhaps. Ah, I just saw the integral, but unfortunately I don't see immediately that it is the Laplace transform of J_{nu} (50 seconds later) OH, now I see what you mean more clearly, though I'd want to work it out. Yeah, Erdelyi would probably have something on it, speaking of which, I should probably add Erdelyi to my book collection.

i feel like i have run into that Laplace transform on this site before

hmm, not quite: math.stackexchange.com/questions/3981862/…

Not quite that one, unfortunately. I remember seeing something in a book on special functions, but I can't recall which one.

Anyway, this went into the hot network queue.

Low quality Although there is context in the comments.

@TeresaLisbon i don't mind that as a question too much (it's mediocre not bad imo) but as ever the hot network queue is inscrutable

@Semiclassical You're right, it's not the worst, but it's definitely debatable, so many better questions can go into the HNQ than that.

right

@SmokeDetector I have reverted the attempt to vandalize the question.

Unclear and/or too broad in my opinion: math.stackexchange.com/q/4282882/42969.

The question asks for the “widest possible choices” of series of decreasing non-negative terms.

@amWhy That question can be deleted now: math.stackexchange.com/q/4280200/42969.

@user2661923 I voted to undelete the question. Of course, you could as well, if you think it's worth it. Also, the question was automatically deleted by the Community user, which I think only happens to closed questions with no upvotes. So, if you think a question is interesting enough to answer and maintain, then it's probably worth your upvote as well.

I am still new to the site, anybody recommends to what to respond to a comment like this, thanks in advance.

and I noticed he doesn't use mathjax in any of his question

@TeresaLisbon open for deletion

@user2661923 Too little is known about this virus for a reasonable statistical model. Therefore, I do not think that it should be undeleted.

@user2661923 (1) When you make a request involving a question which you have either asked or answered, please disclose this fact. (2) The question is a problem statement question, hence was appropriately deleted. (3) I don't see how it is a "highly relevant Covid question." It is, in fact, a very standard exercise from an intro stats class (I've put something similar on most stats finals I've written).
