comment sufficient condition of complete intersection
Are your intersections set-theoretic or scheme-theoretic? If it is the latter, then the answer is yes simply by definition.

comment Waring's problem
That talk is quite a few years old now; Trevor has made a lot of progress on such problems recently using efficient congruencing and I would not be surprised if better bounds were known. Certainly I recommend to the OP to look at the papers on Trevor's webpage.

comment Zeta functions with Brauer class
I'm confused by your assumptions: do you assume that $X$ and $Y$ are both smooth over $\mathbb{Z}$? Such schemes are quite rare.

comment Fermat's last theorem over larger fields
Trivial comment: A similar argument gives infinitely many points over $k^{\mathrm{ab}}$, where $k$ is the fifth cyclotomic field.

comment Fermat's last theorem over larger fields
Ari: I think the problem with your argument is that the cover $X \to \mathbb{P}^1$ not a Galois cover (i.e. the extension of function fields is not Galois). This is due to the reason that René gives, namely $\mathbb{Q}$ does not contain the fifth roots of unity.

comment Underlying idea for (automorphic) L-function?
In which case, I don't understand what your question is. At the moment it seems quite broad, and it's not clear to me what kind of answer you are expecting.

comment Underlying idea for (automorphic) L-function?
My point was that the Selberg class (arguably) gives an answer to your first question. Namely it formalises "the (conjectural) underlying idea of what an $L$-function is".

comment The Diophantine equation $x^2 + bxy + cy^2 = p^z_1 \cdots p^{z_k}$
It seems difficult to imagine an algorithm which could enumerate such a possibly infinite set. Certainly there is a very simple algorthim which will find all solutions given an infinite amount of time.

comment Faltings height in short exact sequences
Well as I said (or at least tried to say), it was my first naive idea on how to approach the problem. If you have already considered this approach, then you probably understand better than me what is going on. Do you believe that the stated equality holds? How hard have you tried to construct counter-examples?
