comment Writing an abstract
Without knowing the details, it seems pretty standard. An abstract should be a brief, but at least mildly informative, statement of what the contents of the paper are; so that someone reading the abstract will get a reasonable idea of whether the contents are of interest to them.

comment A number theory question related to algebraic graph theory?
I'm voting to close this question as off-topic because the author posted a new question rather than editing this one; but I can't find another "reason" for closing besides this one.

\cdots is incorrect inside the cycles, since they should be aligned with the commas

comment A question about (unicity of certain cycles in a Cayley graph of a) symmetric group
@AmirSagiv: If it were meant to be the subgroup generated, then it would be equal to all of $S_n$ (in fact, the first two already generate $S_n$). So surely not: he's asking about expressing the identity as a word in the elements of the subset $S$ with specific constraints.

comment Noetherian almost Dedekind domain
(cont) "Clearly, Dedekind domains are almost Dedekind. The point of the designation is that almost Dedekind domains satisfy the characterization given above of Dedekind domains, except they are not assumed to be Noetherian." This would suggest that not only is the statement true, but in fact it was the impetus behind the definition.

comment Noetherian almost Dedekind domain
In "Almost Dedekind domains which are not Dedekind", Multiplicative ideal theory in commutative algebra, 279–292, Springer, New York, 2006, K. Alan Loper says: "A domain $D$ is a Prufer domain if $D_M$ is a valuation domain for each maximal ideal $M$ of $D$. The Noetherian Prufer domains are the Dedekind domains. It follows that if $D$ is a Dedekind domain, then $D_M$ is a Noetherian valuation domain for each maximal ideal $M$ of $D$. A domain $D$ is almost Dedekind if $D_M$ is a Noetherian valuation domain for each maximal ideal $M$ of $D$. (cont)"

comment Are the positive multiplicative group and the additive group of the field of algebraic numbers isomorphic?
@abx I said "(rational) primes". In algebraic number theory, this is the way one refers to the primes in ℤ (to distinguish them from prime elements or prime ideals in other number fields). So it's not "prime in F". It's the usual prime integers.

@abx: In $\mathbb{Z}$; raise to a power to clear all denominators in the $q_i$, and that gives you an expression for $1$ as a product of (integral) powers of primes.
