Let $q$ be a prime power, let $r$ and $v$ be integers, and let $\mathcal{S}$ be a $q^r$-divisible set of $q^{r+1}$ points in $\operatorname{PG}(v-1,q)$. An $(r+1)$-cylinder is the…

Let $q^t=p^h$, where $p$ is prime. A small minimal blocking set in the projective space $\mathrm{PG}(n-1,q^t)$ is a minimal blocking set satisfying the usual smallness condition, a…
