$f(1) = \zeta(2)$. Why are you saying $f$ is not analytic near $1$?

That does give an analytic function in the interior. But what about its behavior on the boundary? You don't know what happens.

A side question: Is the Mori program part of the minimal model program?

It seems the questioner knows only about Chap. I of Hartshorne's book, for instance.

I still prefer this answer, as it looks more "arithmetical" and I need to understand one thing less for figuring this out. Sorry if this erodes your opinion of me.

MO is asking me to choose an answer. I myself do not know which is the best one; however I am leaning towards this one as it is not using formal groups. If someone more learned would give suggestions, my job would be easier. Or maybe I should wait for longer time?

You know what I meant, there should be a site called csoverflow.net or complexityoverflow.net .. I didn't ask the OP to go and post in stackoverflow. And yes, I also understand the distinction between computational complexity and the rest of computer science. But you have to put an egg in some basket. You cannot break it in two and put in two baskets.

Yeah, if as Ilya says there is really no stackoverflow site for CS, then it could be posted here. But there really ought to be one. And it is not that Cs guys cannot make one.

It would be nice if you put the math inside dollars, and make the appropriate changes for suiting LaTeX.

Every science is part of philosophy. Try posting a question from here in one of the philosophy forums. There is reason why universities run different departments for math and cs sometimes, though cs has a lot in common with math.

Well, I had sorta imagined that since CS guys are so far ahead of mathematics guys in the matter of computer applications and web development, there should be a lot more and much better and focussed resources for CS existing already.

When there are numerous other resources for computer science, are such questions appropriate for MO?

A feeble joke: If only the tower of Babel was not built. ..

This is a really good article. Thanks for posting. The Italian is not hard. Also the really good thing is the detailed bibliography in the end.

Btw, I myself belong to the category mentioned above. Russophile, but not Russophile enough to put in the trouble of learning the language. It seems, as each days passes, I seem to be coming across more and more Russian articles, and one day I will be forced to take the plunge!
