$r$-Critical Numbers of Natural Intervals [PDF]

open access: yesThe 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
