comment Can the sum $1+2+3+\cdots$ be something else than $-1/12$?
The result/derivations depend largely on the assumptions you make. And from Wikipedia it seems if you use both linearity and stability (as in your case), you easily get contradictions. However, they mention two methods which use only one of the properties and yet both get $-1/12$. So, will all methods using linearity XOR stability get the same result? This seems more interesting.

comment Can the sum $1+2+3+\cdots$ be something else than $-1/12$?
The wikipedia page says, that of course this series cannot be treated as linear and stable. Are there any derivations which don't use these two properties?

Sure. But with additional assumptions, apparently you can get an answer that might be even useful. So the question is whether there are two contradictory, but sensible assumptions possible.

Thanks. I have to check that. Looks like one of the most useful answers here :)

comment Prove that 1+1=2
@Asaf: I actually had seen that answer some time ago. It's clear. But the referenced proof seems to go a step beyond?! Your proof isn't that "long" :)

Ah, that reminds me of en.wikipedia.org/wiki/Mellin_transform

comment An inverse definite integral problem
A random idea would be to square it and then compare to the definition of the Gamma function. Of course transform variable to polar coordinates or so...

Interesting. Never thought about it :)
