Almost Self-Complementary Uniform Hypergraphs

open access: yesDiscussiones Mathematicae Graph Theory, 2018
A k-uniform hypergraph (k-hypergraph) is almost self-complementary if it is isomorphic with its complement in the complete k-uniform hypergraph minus one edge. We prove that an almost self-complementary k-hypergraph of order n exists if and only if (nk)$\

Almost Self-Complementary 3-Uniform Hypergraphs

open access: yesDiscussiones Mathematicae Graph Theory, 2017
It is known that self-complementary 3-uniform hypergraphs on n vertices exist if and only if n is congruent to 0, 1 or 2 modulo 4. In this paper we define an almost self-complementary 3-uniform hypergraph on n vertices and prove that it exists if and ...

Edge Balanced 3-Uniform Hypergraph Designs

open access: yesMathematics, 2020
In this paper, we completely determine the spectrum of edge balanced H-designs, where H is a 3-uniform hypergraph with 2 or 3 edges, such that H has strong chromatic number χs(H)=3.

The existence of bipartite almost self-complementary 3-uniform hypergraphs [PDF]

open access: yesOpuscula Mathematica, 2023
An almost self-complementary 3-uniform hypergraph on \(n\) vertices exists if and only if \(n\) is congruent to 3 modulo 4 A hypergraph \(H\) with vertex set \(V\) and edge set \(E\) is called bipartite if \(V\) can be partitioned into two subsets \(V_1\

Constructing and sampling partite, 3-uniform hypergraphs with given degree sequence. [PDF]

open access: yesPLoS ONE
Partite, 3-uniform hypergraphs are 3-uniform hypergraphs in which each hyperedge contains exactly one point from each of the 3 disjoint vertex classes. We consider the degree sequence problem of partite, 3-uniform hypergraphs, that is, to decide if such ...

Super edge-magic labeling for 𝒌-uniform, complete 𝒌-uniform and complete 𝒌-uniform 𝒌-partite hypergraphs [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2021
Let 𝐻 be a hypergraph with a vertex set 𝑉 and a hyperedge set 𝐸. Generalized from the super edge-magic in a graph, we say that a hypergraph 𝐻 is super edge-magic if there is a bijection 𝑓: 𝑉 ∪ 𝐸 → {1,2,3, … , |𝑉| + |𝐸|} which satisfies: (i) there exists

A hyperedge coloring and application in combinatorial testing

open access: yesAKCE International Journal of Graphs and Combinatorics, 2022
For a hypergraph H, a uniform k-coloring of hyperedges always has the same (to within 1) number of hyperedges of each color, whereas an equitable k-coloring of hyperedges has the property that at every vertex all the colors incident the same number of ...

Even order uniform hypergraph via the Einstein product

open access: yesAKCE International Journal of Graphs and Combinatorics, 2023
We propose the algebraic connectivity of an undirected 2m-uniform hypergraph under the Einstein product. We generalize the algebraic connectivity to a directed 2m-uniform hypergraph and reveal the relationship between the vertex connectivity and the ...
