Sperner systems with restricted differences

Zixiang Xu, Chi Hoi Yip

Let $F$ be a family of subsets of $[n]$ and $L$ be a subset of $[n]$ . We say $F$ is an $L$ -differencing Sperner system if $∣ A ∖ B ∣ \in L$ for any distinct…

Intersective sets over abelian groups

Zixiang Xu, Chi Hoi Yip

Given a finite abelian group $G$ and a subset $J \subset G$ with $0 \in J$ , let $D_{G} (J, N)$ be the maximum size of $A \subset G^{N}$ such that the difference set $A - A$ and $J^{N}$ ha…
