Generalized Hyperfocused Arcs in $P G (2, p)$

A. Blokhuis, G. Marino, F. Mazzocca

A {\em generalized hyperfocused arc} $H$ in $P G (2, q)$ is an arc of size $k$ with the property that the $k (k - 1) /2$ secants can be blocked by a set of $k - 1$ points not belo…

A Minimum problem for finite sets of real numbers with non-negative sum

Giampiero Chiaselotti, Giuseppe Marino, Caterina Nardi

Let $n$ and $r$ be two integers such that $0 < r \leq n$ ; we denote by $γ (n, r)$ [ $η (n, r)$ ] the minimum [maximum] number of the non-negative partial sums of a sum $\sum_{1=1}^n a_i \…
