List (d,1)-total labelling of graphs embedded in surfaces [PDF]

open access: yes, 2011
The (d,1)-total labelling of graphs was introduced by Havet and Yu. In this paper, we consider the list version of (d,1)-total labelling of graphs. Let G be a graph embedded in a surface with Euler characteristic $\epsilon$ whose maximum degree $\Delta(G)

Radio Graceful Labelling of Graphs

open access: yesTheory and Applications of Graphs, 2020
Summary: Radio labelling problem of graphs have their roots in communication problem known as Channel Assignment Problem. For a simple connected graph \(G=(V(G),E(G))\), a radio labeling is a mapping \(f:V(G)\to \{0,1,2,\dots\}\) such that \(|f(u)-f(v)|\ge\text{diam}(G)+1-d(u,v)\) for each pair of distinct vertices \(u,v\in V(G)\), where \(\text{diam ...

Minimal Sum Labeling of Graphs [PDF]

open access: yesJournal of Discrete Algorithms, 2018
A graph $G$ is called a sum graph if there is a so-called sum labeling of $G$, i.e. an injective function $\ell: V(G) \rightarrow \mathbb{N}$ such that for every $u,v\in V(G)$ it holds that $uv\in E(G)$ if and only if there exists a vertex $w\in V(G)$ such that $\ell(u)+\ell(v) = \ell(w)$. We say that sum labeling $\ell$ is minimal if there is a vertex

Edge even graceful labelling of new families of graphs

open access: yesJournal of Taibah University for Science, 2019
Elsonbaty and Daoud introduced a new type of labelling of a graph G with p vertices and q edges called an edge even graceful labelling. A graph G is called edge even graceful if there is a bijection $f: E(G) \rightarrow \{2, 4,\ldots , 2q\} $ such that ...

The Distance Irregular Reflexive k-Labeling of Graphs

open access: yesCauchy: Jurnal Matematika Murni dan Aplikasi, 2023
A total k-labeling is a function fe from the edge set to the set {1, 2, . . . , ke} and a function fv from the vertex set to the set {0, 2, 4, . . . , 2kv}, where k = max{ke, 2kv}.

Neutrosophic Labeling Graph

open access: yesNeutrosophic Sets and Systems, 2019
In this paper, some new connectivity concepts in neutrosophic labeling graphs are portrayed. Definition of neutrosophic strong arc, neutrosophic partial cut node, Neutrosophic Bridge and block are introduced with examples. Also, neutrosophic labeling tree and partial intuitionistic fuzzy labeling tree is explored with interesting properties.

The reflexive edge strength on some almost regular graphs

open access: yesHeliyon, 2021
A function f with domain and range are respectively the edge set of graph G and natural number up to ke, and a function f with domain and range are respectively the vertex set of graph G and the even natural number up to 2kv are called a total k-labeling
