Thanks for your answer ! What kind of law is Z ? Can it be a normal distribution ?

comment Confidence interval of a random variable with infinite mean. (St. Petersburg paradox)
If you have a probability law for each $n$, you can always compute $a_p(n)$ and $b_p(n)$ for each $n$, so I don't understand your point.

I'm not sure to understand your question.

One day passed, and not even a comment ? I hoped that it was a well known subject. Is it really a difficult question ??

comment Gödel Completeness theorem
Does someone have a link on a course (or reference of a book(s)) that would explains all those things to me about completeness theorem and integer models ?

comment Gödel Completeness theorem
Ok, so I really did not understand the completeness theorem. And if I define integers as S(S(... S(0))), I'm not sure how I can have different models, but If you have some links about different models of such integers, it will be very interesting for me, as I only found articles about different models of integers in Peano (where integers are not forced to be some finite successor of 0).

comment Gödel Completeness theorem
So if I understand your answer : Completeness theorem only applies to first-order theories ? And (shame on me) why the axiom of infinity in ZF is not first order ?

comment Effective Well ordering of reals
I'm not a first rate set theorist, nor even second or third (omegath perhaps). But thank you for your answer, it is very useful to me :)

Thanks for the math overflow link, this is the answer I needed, and there are links to nice articles. Thank you !

comment Effective Well ordering of reals
Yeah, I deleted my comment. But saying there is a consistent axiom that says "there is no definable well ordering" is not enough (no ?) to say there is no consistent axiom that says "there is one way to define..."
