Makes me wonder what goes on in the minds of people, when they close questions with some mathematical content and lets off questions like mathoverflow.net/questions/29323/math-puzzles-for-dinner without any obstruction.

@Victor: What the OP asked is not a trivial matter. So thinks Andre Weil too. In his autobiography he writes that "what is 'x'?" is a profound question.

I have voted to reopen, btw. That makes it two votes.

Why was this question closed? It doesn't see that the OP is a troll. IT seems the question was a genuine confusion and satisfactory answers are given below. It was very mean to close it without at least directing the OP to math.stackexchange.com or sites of similar level.

That particular definition is the whole reason why Lebesgue is given so much credit. If I remember correctly, it was in his Ph D thesis that he gave that definition. The work of Caratheory, I think, is in showing that it can be done in a more general setting.

@Andrew L: Even in your repentant comments regarding your spelling and punctuation, you are not putting spaces after your dots or commas.

For the sake of completeness: Here's the MR link for Deligne's proof for K3 surfaces: ams.org/mathscinet-getitem?mr=296076

There is a notion of "Parabolic bundle" in algebraic geometry, considered by Seshadri and others. You might find that relevant.

@Junkie. Thanks. I didn't know that it could be obtained using merely Gelfond-Schneider. But it seems the case that Baker's theorem got its fame firstly through this achievement, if I am not mistaken.
