comment Trivial zeroes of the Riemann Zeta function are simple
Just goes to show, you can't believe everything you read on math.stackexchange. In my defense, I'd suggest there's a difference between extending the zeta-function step-by-step, taking an infinity of steps, and extending it all in one go. Anyway, I have now linked the m.se question to this one.

comment What is the maximum size of a set system where the intersection of any two incomparable members is not in the set?
Have you tried finding it for small values of $n$, and then looking it up in the Online Encyclopedia of Integer Sequences?

comment The maximum lengthed sequence of prime numbers with certain conditions (denizens)
There's a theorem that says you can't partition the integers into finitely many arithmetic progressions with different common differences. An IRDCS is a partition of a finite segment of the integers into arithmetic progressions with different common differences, so it shows you can't weaken the theorem hypotheses too much. The numbers were chosen because they work: there is no IRDCS shorter than length 11, and the only one of length 11 is the one I gave, and its reverse. Try it!

comment The maximum lengthed sequence of prime numbers with certain conditions (denizens)
Distantly related: some years ago, my co-authors and I defined the concept of an IRDCS of length $n$. The smallest example, of length 11, is $6,9,3,4,5,3,6,4,3,5,9$. Note that for each $m$ appearing in the list, $m$ appears at every $m$th position, and only at every $m$th position; also, every $m$ that appears appears at least twice.

comment Have any author ever distinguish between “good” and “bad” “indeterminate forms”?
You write that the definitions don't break anything much. I write that they break "$a/b=c$ implies $a=bc$." I guess we have different ideas of what constitutes "anything much".

comment Have any author ever distinguish between “good” and “bad” “indeterminate forms”?
I've gotten used to $a/b=c$ implying $a=bc$. If $\infty/\infty=0$, that leads me to $\infty=\infty\cdot0$.

How can you have both $0\cdot\infty=0$ and $\infty/\infty=0$?

comment Bost's slopes method for Lindemann theorem
So, maybe what you are looking for, doesn't exist. Do you have some reason to believe there is a proof of Lindemann somewhere that uses Bost?
