Some intriguing upper bounds for separating hash families

Gennian Ge, Chong Shangguan, Xin Wang

An $N \times n$ matrix on $q$ symbols is called ${w_{1}, \dots, w_{t}}$ -separating if for arbitrary $t$ pairwise disjoint column sets $C_{1}, \dots, C_{t}$ with $∣ C_{i} ∣ = w_{i}$ for $1\le i\le t…

Sparse hypergraphs: new bounds and constructions

Gennian Ge, Chong Shangguan

Let $f_{r} (n, v, e)$ denote the maximum number of edges in an $r$ -uniform hypergraph on $n$ vertices, in which the union of any $e$ distinct edges contains at least $v + 1$ vertices. The…
