Excellent! For some reason I did not remember this refinement.

Automorphism group of the gamma factor of a certain type of Lfunction
There is no polynomial "defining the Euler product". Each Euler factor (at a prime $p$) is a different polynomial (of $p^{s}$), and these are quite independent of each other and of the gamma factor. In fact the gamma factor is usually thought of as the Euler factor at the infinite prime $\infty$.

Onetoone correspondance between zeta zeros and the prime powers?
Don't worry about bumps. Readers appreciate the effort put into a question.

I think you should update a question as long as you can improve it. Updating is fun and useful.

Onetoone correspondance between zeta zeros and the prime powers?
Well, it is still unfortunate to call $r_n$ the $n$th solution $x$, while $n$ is the running variable for the zeros as well. That is, $r_n$ should be called $x_m$ and at appropriate (but not all) places $n$ should be called $m$ accordingly.

What do you mean by "the first display holds for the $n$th $\rho$"? The first display involves a sum of $\rho$'s, not a single $\rho$. At any rate, please update the question with appropriate notation. Thanks!

Do you mean that $r$ is a value $x$ at which the first display holds? There is no $r$ in that equation, that's why I am asking. Similarly, there is no $r$ in your second equation. The question is unclear to me.

How to write an abstract for a math paper?
I think the abstract is supposed to summarize, not advertise the paper.

A curious determinantal inequality
Very nice proof! It would be interesting to see a "coordinate free" proof in the spirit of the SchurHorn theorem, but probably it would not be any simpler than this one (especially that your proof is selfcontained).
