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…

A strengthened inequality of Alon-Babai-Suzuki's conjecture on set systems with restricted intersections modulo p

Xin Wang, Hengjia Wei, Gennian Ge

Let $K = {k_{1}, k_{2}, \dots, k_{r}}$ and $L = {l_{1}, l_{2}, \dots, l_{s}}$ be disjoint subsets of ${0, 1, \dots, p - 1}$ , where $p$ is a prime and $A = {A_{1}, A_{2}, \dots, A_{m}}$ be a family of subset…
