Local edge (a, d) –antimagic coloring on sunflower, umbrella graph and its application

open access: yesAlifmatika, 2023
Suppose a graph G = (V, E) is a simple, connected and finite graph with vertex set V(G) and an edge set E(G). The local edge antimagic coloring is a combination of local antimagic labelling and edge coloring.

(Di)graph products, labelings and related results [PDF]

open access: yes, 2017
Gallian's survey shows that there is a big variety of labelings of graphs. By means of (di)graphs products we can establish strong relations among some of them.

Lexicographic product graphs P m [ P n ] are antimagic

open access: yesAKCE International Journal of Graphs and Combinatorics, 2018
A graph with q edges is called a n t i m a g i c if its edges can be labeled with 1, 2, …, q such that the sums of the labels on the edges incident to each vertex are distinct.

Antimagicness for a family of generalized antiprism graphs

open access: yesElectronic Journal of Graph Theory and Applications, 2014
An antimagic labeling of a graph $G=(V,E)$ is a bijection from the set of edges $E$ to the set of integers $\{1,2,\dots, |E|\}$ such that all vertex weights are pairwise distinct, where the weight of a vertex is the sum of all edge labels incident with ...

Ideal Basis in Constructions Defined by Directed Graphs [PDF]

open access: yes, 2015
The present article continues the investigation of visible ideal bases in constructions defined using directed graphs. This notion is motivated by its applications for the design of classication systems.

Antimagic Orientation of Biregular Bipartite Graphs

open access: yesThe Electronic Journal of Combinatorics, 2017
An antimagic labeling of a directed graph $D$ with $n$ vertices and $m$ arcs is a bijection from the set of arcs of $D$ to the integers $\{1, \cdots, m\}$ such that all $n$ oriented vertex sums are pairwise distinct, where an oriented vertex sum is the sum of labels of all arcs entering that vertex minus the sum of labels of all arcs leaving it.

Integer-antimagic spectra of disjoint unions of cycles

open access: yesTheory and Applications of Graphs, 2018
Let $A$ be a non-trivial abelian group. A simple graph $G = (V, E)$ is $A$-antimagic if there exists an edge labeling $f: E(G) \to A \setminus \{0\}$ such that the induced vertex labeling $f^+: V(G) \to A$, defined by $f^+(v) = \sum_{uv\in E(G)}f(uv ...

Vertex-antimagic total labelings of graphs

open access: yesDiscussiones Mathematicae Graph Theory, 2003
The paper introduces a new type of labeling, the \((a,d)\)-vertex-antimagic total labeling. Let \(G\) be a graph with \(n\) vertices and \(e\) edges. Assign different labels to every edge and every vertex of the graph from the set \(\{1,2,\dots,n+ e\}\). For every vertex add the label of the vertex and the labels of the incident edges.
