Super edge-magic labeling of m-node k-uniform hyperpaths and m-node k-uniform hypercycles

open access: yesAKCE International Journal of Graphs and Combinatorics, 2016
We generalize the notion of the super edge-magic labeling of graphs to the notion of the super edge-magic labeling of hypergraphs. For a hypergraph H with a finite vertex set V and a hyperedge set E, a bijective function f:V∪E→{1,2,3,…,|V|+|E|} is called

Colorful Subhypergraphs in Uniform Hypergraphs

open access: yesThe Electronic Journal of Combinatorics, 2017
There are several topological results ensuring in any properly colored graph the existence of a colorful complete bipartite subgraph, whose order is bounded from below by some topological invariants of some topological spaces associated to the graph. Meunier [Colorful subhypergraphs in Kneser hypergraphs, The Electronic Journal of Combinatorics, 2014 ...

The α-Arboricity of Complete Uniform Hypergraphs [PDF]

open access: yesSIAM Journal on Discrete Mathematics, 2011
$\alpha$-Acyclicity is an important notion in database theory. The $\alpha$-arboricity of a hypergraph H is the minimum number of $\alpha$-acyclic hypergraphs that partition the edge set of H. The $\alpha$-arboricity of the complete 3-uniform hypergraph is determined completely.

CFlow: A Novel High‐Order Flow Analysis Unit for Detecting Spatiotemporal Mobility Patterns Based on Origin–Destination Data

open access: yesTransactions in GIS, Volume 29, Issue 3, May 2025.
ABSTRACT Mobility behavior research has long been a focal point in geographic information science (GIS). Many researchers use isolated OD pairs as flow analysis units when studying mobility behavior based on OD (origin–destination) data. However, isolated OD pairs only reflect individual mobility, which may constrain applying a collective analytical ...

Hypergraph removal lemmas via robust sharp threshold theorems

open access: yesDiscrete Analysis, 2020
Hypergraph removal lemmas via robust sharp threshold theorems, Discrete Analysis 2020:10, 46 pp. A central result in additive and extremal combinatorics is the triangle removal lemma, which roughly speaking states that a graph with few triangles can be ...

EIGENVALUES AND LINEAR QUASIRANDOM HYPERGRAPHS

open access: yesForum of Mathematics, Sigma, 2015
Let $p(k)$ denote the partition function of $k$. For each $k\geqslant 2$, we describe a list of $p(k)-1$ quasirandom properties that a $k$-uniform hypergraph can have. Our work connects previous notions on linear hypergraph quasirandomness by Kohayakawa,

Hypergraphs with infinitely many extremal constructions

open access: yesDiscrete Analysis, 2023
Hypergraphs with infinitely many extremal constructions, Discrete Analysis 2023:18, 34 pp. A fundamental result in extremal graph theory, Turán's theorem, states that the maximal number of edges of a graph with $n$ vertices that does not contain a ...

Linear trees in uniform hypergraphs

open access: yesEuropean Journal of Combinatorics, 2014
Given a tree T on v vertices and an integer k exceeding one. One can define the k-expansion T^k as a k-uniform linear hypergraph by enlarging each edge with a new, distinct set of (k-2) vertices. Then T^k has v+ (v-1)(k-2) vertices. The aim of this paper is to show that using the delta-system method one can easily determine asymptotically the size of ...
