The Hilton-Milner type results of $(k, ℓ)$ -sum-free sets in $F_{p}^{n}$

Xin Wei, Xiande Zhang, Gennian Ge

For a prime $p \equiv 2 (mod 3)$ , it is well known that the largest sum-free subsets of $F_{p}^{n}$ have size $\frac{p + 1}{3} p^{n - 1}$ , and the extremal sets must be a cuboid o…

Analytic Characterization of $t$ -Quasicircles and Conformal Mappings onto $t$ -Quasidisks

Xin Wei

In this paper, we introduce a new class of mappings, termed $(ρ, t)$ -quasisymmetric mappings, which generalizes the classical concept of quasisymmetric mappings. Using this broader…

On set systems with strongly restricted intersections

Xin Wei, Xiande Zhang, Gennian Ge

Set systems with strongly restricted intersections, called $α$ -intersecting families for a vector $α$ , were introduced recently as a generalization of several well-studied intersec…

Separating hash families with large universe

Xin Wei, Xiande Zhang, Gennian Ge

Separating hash families are useful combinatorial structures which generalize several well-studied objects in cryptography and coding theory. Let $p_{t} (N, q)$ denote the maximum siz…

Swap-Robust and Almost Supermagic Complete Graphs for Dynamical Distributed Storage

Xin Wei, Xiande Zhang, Gennian Ge

To prevent service time bottlenecks in distributed storage systems, the access balancing problem has been studied by designing almost supermagic edge labelings of certain graphs to…

On supersaturation for oddtown and eventown

Xin Wei, Yuhao Zhao, Xiande Zhang +1

We study the supersaturation problems of oddtown and eventown. Given a family $A$ of subsets of an $n$ element set, let $o p (A)$ denote the number of distinct pair…

Optimal Ternary Codes with Weight $w$ and Distance $2 w - 2$ in $ℓ_{1}$ -Metric

Xin Wei, Tingting Chen, Xiande Zhang

The study of constant-weight codes in $ℓ_{1}$ -metric was motivated by the duplication-correcting problem for data storage in live DNA. It is interesting to determine the maximum s…

Covering Radius of Permutation Groups with Infinity-Norm

Xin Wei, Xiande Zhang

The covering radius of permutation group codes are studied in this paper with $l_{\infty}$ -metric. We determine the covering radius of the $(p, q)$ -type group, which is a direct pro…
