D-Antimagic Labelings of Oriented Star Forests [PDF]

open access: yes
For a distance set $D$, an oriented graph $\overrightarrow{G}$ is $D$-antimagic if there exists a bijective vertex labeling such that the sum of all labels of $D$-out-neighbors is distinct for each vertex.

Every connected graph admits a local antimagic orientation and almost every graph admits an antimagic orientation [PDF]

open access: yes
An undirected graph $G$ is said to admit an antimagic orientation if there exist an orientation $D$ and a bijection between $E(G)$ and $\{1,2,\ldots,|E(G)|\}$ such that any two vertices have distinct vertex sums, where the vertex sum of a vertex is the ...

D-Antimagic Labelings on Oriented Linear Forests [PDF]

open access: yes
Let $\overrightarrow{G}$ be an oriented graph with the vertex set $V(\overrightarrow{G})$ and the arc set $A(\overrightarrow{G})$. Suppose that $D\subseteq \{0,1,\dots,\partial \}$ is a distance set where $\partial=\max \{d(u,v)

On k-shifted antimagic spider forests [PDF]

open access: yes, 2021
Let G(V,E) be a simple graph with m edges. For a given integer k, a k-shifted antimagic labeling is a bijection f:E(G)→{k+1,k+2,…,k+m} such that all vertices have different vertex-sums, where the vertex-sum of a vertex v is the total of the labels ...

The antimagic orientation problems for graphs obtained by some graph operations [PDF]

open access: yes, 2022
A simple graph $G$ is said to admit an antimagic orientation if there exist an orientation on the edges of $G$ and a bijection from $E(G)$ to $\{1,2,\ldots,|E(G)|\}$ such that the vertex sums of vertices are pairwise distinct, where the vertex sum of a ...

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.

Antimagic Labeling of Some Biregular Bipartite Graphs [PDF]

open access: yes, 2022
An antimagic labeling of a graph G = (V, E) is a one-to-one mapping from E to {1, 2, . . ., |E|} such that distinct vertices receive different label sums from the edges incident to them. G is called antimagic if it admits an antimagic labeling.

Edge-antimagic graphs [PDF]

open access: yes, 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 ...

Shifted-Antimagic Labelings for Graphs [PDF]

open access: yes, 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.
