Parallel multilevel constructions for constant dimension codes

Shuangqing Liu, Yanxun Chang, Tao Feng

Constant dimension codes (CDCs), as special subspace codes, have received a lot of attention due to their application in random network coding. This paper introduces a family of ne…

Triangle decompositions of $λ K_{v} - λ K_{w} - λ K_{u}$

Yueting Li, Yanxun Chang, Tao Feng

Denote by $λ K_{v}$ the complete graph of order $v$ with multiplicity $λ$ . Let $λ K_{v} - λ K_{w} - λ K_{u}$ be the graph obtained from $λ K_{v}$ by the removal of the edges of two vertex disjoint co…

Leaves for packings with block size four

Yanxun Chang, Peter J. Dukes, Tao Feng

We consider maximum packings of edge-disjoint $4$ -cliques in the complete graph $K_{n}$ . When $n \equiv 1$ or $4 (mod 12)$ , these are simply block designs. In other congruence class…

Strong difference families of special types

Yanxun Chang, Simone Costa, Tao Feng +1

Strong difference families of special types are introduced to produce new relative difference families from the point of view of both asymptotic existences and concrete examples. A…

New bounds on the maximum size of Sperner partition systems

Yanxun Chang, Charles J. Colbourn, Adam Gowty +2

An $(n, k)$ -Sperner partition system is a collection of partitions of some $n$ -set, each into $k$ nonempty classes, such that no class of any partition is a subset of a class of any…
