Orientable Z_n-distance magic labeling of the Cartesian product of many cycles [PDF]

open access: yesElectronic Journal of Graph Theory and Applications, 2017
The following generalization of distance magic graphs was introduced in [2]. A directed Z_n-distance magic labeling of an oriented graph $\overrightarrow{G}=(V,A)$ of order n is a bijection $\overrightarrow{\ell}\colon V \rightarrow Z_n$ with the ...

Distance Magic Labeling of Corona Product of Graphs

open access: yesInPrime
Let G = (V, E) is a graph with order n, and f: V(G) → {1,2,...,n} is a bijection. For any vertex v ϵ V, the sum of f(u) is called the weight of vertex v, denoted by w(v), where N(v)  is the set of neighbors of vertex v.

Orientable -distance magic regular graphs

open access: yesAKCE International Journal of Graphs and Combinatorics, 2021
Hefetz, Mütze, and Schwartz conjectured that every connected undirected graph admits an antimagic orientation (Hefetz et al., 2010). In this paper we support the analogous question for distance magic labeling. Let be an Abelian group of order .

Some distance magic graphs

open access: yesAKCE International Journal of Graphs and Combinatorics, 2018
A graph G = ( V , E ) , where | V | = n and | E | = m is said to be a distance magic graph if there exists a bijection from the vertex set V to the set { 1 , 2 , … , n } such that, ∑ v ∈ N ( u ) f ( v ) = k , for all u ∈ V , which is a constant and ...

On 14-regular distance magic graphs

open access: yesElectronic Journal of Graph Theory and Applications
Let G be a graph with n vertices. By N(v) we denote the set of all vertices adjacent to v. A bijection f : V(G)→{1, 2, …, n} is a distance magic labeling of G if there exists an integer k such that the sum of labels of all vertices adjacent to v is k for

On distance labelings of 2-regular graphs

open access: yesElectronic Journal of Graph Theory and Applications, 2021
Let G  be a graph with |V(G)| vertices and ψ :  V(G) → {1, 2, 3, ... , |V(G)|} be a bijective function. The weight of a vertex v ∈ V(G) under ψ is wψ(v) = ∑u ∈ N(v)ψ(u).  The function ψ is called a distance magic labeling of G, if wψ(v) is a constant for

D-magic strongly regular graphs

open access: yesAKCE International Journal of Graphs and Combinatorics, 2020
For a set of distances D, a graph G on n vertices is said to be D-magic if there exists a bijection and a constant k such that for any vertex x, where is the D-neighbourhood set of x.

A note on incomplete regular tournaments with handicap two of order n≡8(mod 16) [PDF]

open access: yesOpuscula Mathematica, 2017
A \(d\)-handicap distance antimagic labeling of a graph \(G=(V,E)\) with \(n\) vertices is a bijection \(f:V\to \{1,2,\ldots ,n\}\) with the property that \(f(x_i)=i\) and the sequence of weights \(w(x_1),w(x_2),\ldots,w(x_n)\) (where \(w(x_i)=\sum_{x_i

Distance antimagic labelings of Cartesian product of graphs

open access: yesAKCE International Journal of Graphs and Combinatorics, 2020
Let be a graph of order n. Let be a bijection. The weight w(v) of a vertex v with respect to the labeling f is defined by where N(v) is the open neighborhood of v. The labeling f is called a distance antimagic labeling if for any two distinct vertices v1,

Handicap Labelings of 4-Regular Graphs

open access: yesAdvances in Electrical and Electronic Engineering, 2017
Let G be a simple graph, let f : V(G)→{1,2,...,|V(G)|} be a bijective mapping. The weight of v ∈ V(G) is the sum of labels of all vertices adjacent to v. We say that f is a distance magic labeling of G if the weight of every vertex is the same
