$r$-Critical Numbers of Natural Intervals [PDF]
The Electronic Journal of Combinatorics, 2021 The critical number $cr(r,n)$ of natural intervals $[r,n]$ was introduced by Herzog, Kaplan and Lev in 2014. The critical number $cr(r,n)$ is the smallest integer $t$ satisfying the following conditions: (i) every sequence of integers $S=\{r_1=r\leq r_2\leq \dotsb\leq r_k\}$ with $r_1+r_2 +\dotsb +r_k=n$ and $k\geq t$ has the following property: every

Explicit interval estimates for prime numbers [PDF]
Mathematics of Computation, 2022 Using a smoothing function and recent knowledge on the zeros of the Riemann zeta-function, we compute pairs of ( Δ , x 0 ) (\Delta ,x_0) such that for all x ≥ x 0 x \geq x_0 there exists at least one prime in ...
