comment Find minimal set of progressions which intersections, unions or negations covers given set
What if you take a set with no 3-term APs? There are known examples when such a set is fairly big.

comment Uniform bound for the number primes $p$ s.t. a polynomial has a root modulo $p$
Thanks a lot. So I accept your answer as now I can safely say that without GRH the problem is hard and wide open.

comment Uniform bound for the number primes $p$ s.t. a polynomial has a root modulo $p$
Correct me if I am wrong but it seems that the unconditional version of the Chebotaryov density is just not strong enough to provide the desired bound (and the conditional version does give it), since the power beta goes to 1 as N is large.

comment Number of solutions of linear homogenous Diophantine equation inside a box
Thanks for the nice answer. In fact, it works for all boxes larger than some constant which depend only on $d$ and $c$, which is important since in my case $a_i$ may depend on $N$ but not on the dimension and $c$.

comment Number of solutions of linear homogenous Diophantine equation inside a box
What do you mean by averaging? since the equation is homogeneous one can of course assume that $a_i$ sum up to $1$.

comment Number of solutions of linear homogenous Diophantine equation inside a box
Thanks, but after a quick look it seems that they always assume the coefficients are at least rational, don't they?

comment Separating pairs of points in R^n
And I suppose $n$ in $\mathbb{R}^n$ is not the same $n$ which is the maximal number of points in an open set of diameter 2?

comment How to efficiently sample uniformly from the set of p-partitions of an n-set?
I would imagine that a Markov chain with rapid mixing might be useful here, though it would give only approximately uniform distribution.
