ErdÅs-Ko-Rado-type problem for hypergraph matchings
Binwei Zhao, Tao Feng, Xiaomiao Wang +1
The paper determines the largest possible size of families of k‑matchings in complete r‑partite r‑uniform hypergraphs that intersect in at least t edges, and characterizes the extr…
The maximum size of the partial ground set of skew Bollobás systems
Yu Fang, Tao Feng, Xiaomiao Wang
A skew Bollobás system is a collection of pairs of disjoint subsets of such that for any $1\leq i<j\leq m…
Constructions of two-dimensional optical orthogonal codes of weight three
Xiuling Shan, Lidong Wang, Yanxun Chang +1
The study of optical orthogonal codes has been motivated by an application in an optical code-division multiple access system. This paper focuses on optimal two-dimensional optical…
Perfect difference families, perfect systems of difference sets and their applications
Hengrui Liu, Tao Feng, Xiaomiao Wang +1
Let be a positive odd integer. A -perfect difference family (PDF) is a collection of -subsets of such that the multiset $\bigcup…
