Decompositions of Edge-Colored Digraphs: A New Technique in the Construction of Constant-Weight Codes and Related Families
Yeow Meng Chee, Fei Gao, Han Mao Kiah +3
We demonstrate that certain Johnson-type bounds are asymptotically exact for a variety of classes of codes, namely, constant-composition codes, nonbinary constant-weight codes and…
Pairwise balanced designs with prescribed minimum dimension
Peter J. Dukes, Alan C. H. Ling
The dimension of a linear space is the maximum positive integer such that any of its points generate a proper subspace. For a set of integers at least two, recall that…
A three-factor product construction for mutually orthogonal latin squares
Peter J. Dukes, Alan C. H. Ling
It is well known that mutually orthogonal latin squares, or MOLS, admit a (Kronecker) product construction. We show that, under mild conditions, `triple products' of MOLS can resul…
The fine intersection problem for Steiner triple systems
Yeow Meng Chee, Alan C. H. Ling, Hao Shen
The intersection of two Steiner triple systems (X,A) and (X,B) is the set A intersect B. The fine intersection problem for Steiner triple systems is to determine for each v, the se…
On Extremal k-Graphs Without Repeated Copies of 2-Intersecting Edges
Yeow Meng Chee, Alan C. H. Ling
The problem of determining extremal hypergraphs containing at most r isomorphic copies of some element of a given hypergraph family was first studied by Boros et al. in 2001. There…
