Some Results on Local Distance Antimagic Chromatic Number of Graphs

open access: yes
Let G=(V,E) be a graph of order n without isolated vertices. A bijection f:V -- {1,2,...n} is called a local distance antimagic labeling if the weights of any two adjacent vertices are not equal, where the weight of a vertex is defined to be the sum of ...

On local antimagic chromatic number of the join of two special families of graphs -- II [PDF]

open access: yes
It is known that null graphs and 1-regular graphs are the only regular graphs without local antimagic chromatic number. In this paper, we proved that the join of 1-regular graph and a null graph has local antimagic chromatic number is 3. Consequently, we

Shifted-Antimagic Labelings for Graphs [PDF]

open access: yesGraphs and Combinatorics, 2021
The concept of antimagic labelings of a graph is to produce distinct vertex sums by labeling edges through consecutive numbers starting from one. A long-standing conjecture is that every connected graph, except a single edge, is antimagic. Some graphs are known to be antimagic, but little has been known about sparse graphs, not even trees.

Edge-antimagic graphs

open access: yesDiscrete Mathematics, 2007
For a graph G = (V ,E), a bijection g from V (G) ∪ E(G) into {1, 2, . . . , |V (G)| + |E(G)|} is called (a, d)-edge-antimagic total labeling of G if the edge-weights w(xy) = g(x) + g(y) + g(xy), xy belong to E(G), form an arithmetic progression starting ...

Dense graphs are antimagic [PDF]

open access: yesJournal of Graph Theory, 2004
AbstractAn antimagic labeling of graph a with m edges and n vertices is a bijection from the set of edges to the integers 1,…,m such that all n vertex sums are pairwise distinct, where a vertex sum is the sum of labels of all edges incident with the same vertex. A graph is called antimagic if it has an antimagic labeling. A conjecture of Ringel (see 4)

Graph antimagic labeling: A survey

Discrete Mathematics, Algorithms and Applications, 2023
An antimagic labeling of a simple graph [Formula: see text] is a bijection [Formula: see text] such that [Formula: see text] for any two vertices [Formula: see text] in [Formula: see text]. We survey the results about antimagic labelings and other labelings motivated by antimagic labelings of graphs, and present some conjectures and open questions.

Perfectly antimagic total graphs

Journal of Intelligent & Fuzzy Systems, 2023
An one-one correspondence function λ from V(G) ∪ E(G) to the set {1, 2, …, |V(G) | + |E(G) |} is a total labeling of a finite undirected graph G without loops and multiple edges, where |V(G) |and |E(G) | are the cardinality of vertex and edge set of G respectively.

Antimagic Labeling of Cubic Graphs

Journal of Graph Theory, 2014
Summary: An antimagic labeling of a graph \(G\) is a one-to-one correspondence between \(E(G)\) and \(\{1,2,\ldots,|E|\}\) such that the sum of the labels assigned to edges incident to distinct vertices are different. If \(G\) has an antimagic labeling, then we say \(G\) is antimagic. This article proves that cubic graphs are antimagic.

On antimagic directed graphs

Journal of Graph Theory, 2009
AbstractAn antimagic labeling of an undirected graph G with n vertices and m edges is a bijection from the set of edges of G to the integers {1, …, m} such that all n vertex sums are pairwise distinct, where a vertex sum is the sum of labels of all edges incident with that vertex. A graph is called antimagic if it admits an antimagic labeling.
