Total Edge Irregularity Strength of Arithmetic Book Graphs

open access: yesJournal of Physics: Conference Series, 2019
Abstract For any simple undirected graph G(V, E), a map f : V ⋃ E → {1, 2, …, k} such that for any different edges xy and x’y’ their weights are distinct is called an edge irregular total k-labeling. The weight of edge xy is defined as the sum of edge label of xy, vertex label of x and vertex label of y. The minimum k for which the graph

Computing total edge irregularity strength of some n-uniform cactus chain graphs and related chain graphs

open access: yesIndonesian Journal of Combinatorics, 2020
Given graph G(V,E). We use the notion of total k-labeling which is edge irregular. The notion of total edge irregularity strength (tes) of graph G means the minimum integer k used in the edge irregular total k-labeling of G.

Total Edge Irregularity Strength for Graphs

open access: yes, 2017
An edge irregular total $k$-labelling $f : V(G)\cup E(G)\rightarrow \{1,2,\dots,k\}$ of a graph $G$ is a labelling of the vertices and the edges of $G$ in such a way that any two different edges have distinct weights. The weight of an edge $e$, denoted by $wt(e)$, is defined as the sum of the label of $e$ and the labels of two vertices which incident ...

Generalized Arithmetic Staircase Graphs and Their Total Edge Irregularity Strengths

open access: yesSymmetry, 2022
Let Γ=(VΓ,EΓ) be a simple undirected graph with finite vertex set VΓ and edge set EΓ. A total n-labeling α:VΓ∪EΓ→{1,2,…,n} is called a total edge irregular labeling on Γ if for any two different edges xy and x′y′ in EΓ the numbers α(x)+α(xy)+α(y) and α(x′)+α(x′y′)+α(y′) are distinct. The smallest positive integer n such that Γ can be labeled by a total

Irregular labelings of helm and sun graphs

open access: yesAKCE International Journal of Graphs and Combinatorics, 2015
A vertex irregular total k-labeling of a (p,q)-graph G=(V,E) is a labeling ϕ:V∪E→{1,2,…,k} such that the weights of the vertices wt(v)=ϕ(v)+∑uv∈Eϕ(uv) are different for all vertices.

Total edge irregularity strength of large graphs

open access: yesDiscrete Mathematics, 2012
Let $m:=|E(G)|$ sufficiently large and $s:=(m-1)/3$. We show that unless the maximum degree $ > 2s$, there is a weighting $w:E\cup V\to \{0,1,...,s\}$ so that $w(uv)+w(u)+w(v)\ne w(u'v')+w(u')+w(v')$ whenever $uv\ne u'v'$ (such a weighting is called {\em total edge irregular}).

On cycle-irregularity strength of ladders and fan graphs

open access: yesElectronic Journal of Graph Theory and Applications, 2020
A simple graph G = (V(G),E(G)) admits an H-covering if every edge in E(G) belongs to at least one subgraph of G isomorphic to a given graph H. A total k-labeling φ : V(G) ∪ E(G) → {1,2,..., k} is called to be an H-irregular total k-labeling of the graph ...

The total disjoint irregularity strength of some certain graphs

open access: yesIndonesian Journal of Combinatorics, 2020
Under a totally irregular total k-labeling of a graph G = (V, E), we found that for some certain graphs, the edge-weight set W (E) and the vertex-weight set W (V ) of G which are induced by k=ts(G), W(E)∩W(V) is a non empty set.

Totally irregular total labeling of some caterpillar graphs

open access: yesElectronic Journal of Graph Theory and Applications, 2020
Assume that G(V,E) is a graph with V and E as its vertex and edge sets, respectively. We have G is simple, connected, and undirected. Given a function λ from a union of V and E into a set of k-integers from 1 until k.
