On the blending of real/complex analysis with number theory. The study involves distribution of prime numbers and other problems and helps giving asymptotic estimates to these.

Smallest constant so that there are at least $n/\log_2{n}$ primes between $n$ and a constant...

Indeed, the suggestion given in the other thread is quite appropriate. Use a lower bound from Dusart for $\pi(cn)$, and an upper bound for $\pi(n)$, and you want the difference between these bounds t …

Distribution of composite numbers

I would like to maintain my basic position on the other post: that this forum does not do well with questions that frequently change. Since the last version has hit rather close to home, I will remar …

Distribution of composite numbers

I am afraid the weak version (at this writing) involving density being less than $1/(x-2)$ doesn't work either. Simply pick $d_i$ and $x$ near but less than $\sqrt{N}$, and arrange $K$ and $L$ so tha …

Small quotients of smooth numbers

Here is some (unverified) computational data, which I encourage others to extend. I look at the squarefree p-smooth numbers (being $2^k$ in number for $p$ being the $k$th prime) and compared successi …

Jacobsthal function related to squares

I take back what I said in the comments about the bound not shrinking.  I am convinced that one can get much tighter bounds, and that the tighter bounds will depend massively on the quadratic residues …
