Reopened Annuity immediate and present value I disagree with the reason for closure. There is clear context in the form of a nearly complete (but ultimately incorrect) attempt to answer the question. The only possible reason I can think of that it might have been flagged for closure is that those who voted to close are unaware of the terminology used in ...

Undeleted, Reopened I would like to request that this thread be undeleted and reopened: "If $\#(S)<\#(\Bbb N)$, then prove that $S$ is finite, without using the Axiom of Choice.." I did not answer the question, but I think the thread is useful for people to learn which argument relies on the Axiom of Choice, and which does not.

Undeleted Please undelete Invariance of the Lagrangian vs invariance of its integral It was recently autodeleted by Community because its net vote count was reduced to $0$ by a single vote cast in a recent downvote spree targeting me. I'm still interested in the topic and am looking forward to an answer or two...

Reopened I propose to reopen Which Combinations of Roots of Unity are Zero?, which is a perfectly phrased and interesting question of which I have no idea why it had been closed. There was some debate about whether the questioner meant to ask for real or integer linear combinations of the roots of unity, which is now settled by an edit – it’s about integer ...

May I request to Undelete and Reopen (or at least undelete) this question Prove $\frac{ab}{a^5 + b^5 + ab} + \frac{bc}{b^5 + c^5+ bc} + \frac{ca}{c^5 + a^5 + ca} \leq 1$ when $abc=1$, $a,b,c>0$ answered by me? The question is well written and it's a very tricky inequality.

Reopened Please consider this question Some Combinatorics and Some Prime Numbers to be reopened. This was posted by me seeking for other solutions rather than mine. I think it's well explained.

Reopened Please consider this question Prove that $\gcd\left(n^{a}+1, n^{b}+1\right)$ divides $n^{\gcd(a, b)}+1$ to be reopened. I answered the question. And more context has been given.

Undeleted May I request that this old question Countably Infinitely Many Points in a Euclidean Space of mine be undeleted? The deletion was done by an automatic system (if that is the case, can it be voted to be undeleted?). I am certain that the question is well written with a lot of context. I would like to put a bounty on the question.

Undeleted May I request that this old question GCD of $n^a\,\prod\limits_{i=1}^k\,\left(n^{b_i}-n\right)$ for $n\in\mathbb{Z}$ of mine be undeleted? The deletion was done by an automatic system (if that is the case, can it be voted to be undeleted?). I am certain that the question is well written with a lot of context. I would like to put a bounty on the ...

Undeleted, Reopened Please undelete and reopen Proof of $(1 + \delta)^{1/2 + \delta}(1- \delta)^{1/2 - \delta} > 1$ for $0 < \delta \leq 1/2$?. Let it be known that I answered the question. The question should now have sufficient context.

Undeleted, Reopened I want this question to be to undeleted because I wrote a long answer for it and it was a correct and well-explained question. The question now has more context. Edit: Can someone suggest for edits that should be made to reopen this post also? This problem is quite similar to Siegel's lemma and I don't think MSE has a post regarding ...
