A Note on 1-Edge Balance Index Set [PDF]
, 2012 A graph labeling is an assignment of integers to the vertices or edges or both, subject to certain conditions. Varieties of graph labeling have been investigated by many authors [2], [3] [5] and they serve as useful models for broad range of ...

Note on group distance magic graphs $G[C_4]$ [PDF]
, 2012 A \emph{group distance magic labeling} or a $\gr$-distance magic labeling of a graph $G(V,E)$ with $|V | = n$ is an injection $f$ from $V$ to an Abelian group $\gr$ of order $n$ such that the weight $w(x)=\sum_{y\in N_G(x)}f(y)$ of every vertex $x \in V$

On Face Irregular Evaluations of Plane Graphs
Discussiones Mathematicae Graph Theory, 2022 We investigate face irregular labelings of plane graphs and we introduce new graph characteristics, namely face irregularity strength of type (α,β,γ). We obtain some estimation on these parameters and determine the precise values for certain families of ...

ℤ2 × ℤ2-Cordial Cycle-Free Hypergraphs
Discussiones Mathematicae Graph Theory, 2021 Hovey introduced A-cordial labelings as a generalization of cordial and harmonious labelings [7]. If A is an Abelian group, then a labeling f : V (G) → A of the vertices of some graph G induces an edge labeling on G; the edge uv receives the label f(u) +

, 2011 A graph that admits a Smarandachely super mean m-labeling is called a Smarandachely super m-mean graph, particularly, a mean graph if m = 2. In this paper, some new families of mean graphs are investigated.

Bounds of Strong EMT Strength for certain Subdivision of Star and Bistar
Open Mathematics, 2018 A super edge-magic total (SEMT) labeling of a graph ℘(V, E) is a one-one map ϒ from V(℘)∪E(℘) onto {1, 2,…,|V (℘)∪E(℘) |} such that ∃ a constant “a” satisfying ϒ(υ) + ϒ(υν) + ϒ(ν) = a, for each edge υν ∈E(℘), moreover all vertices must receive the ...

On Total H-Irregularity Strength of the Disjoint Union of Graphs
Discussiones Mathematicae Graph Theory, 2020 A simple graph G admits an H-covering if every edge in E(G) belongs to at least to one subgraph of G isomorphic to a given graph H. For the subgraph H ⊆ G under a total k-labeling we define the associated H-weight as the sum of labels of all vertices and

Trees Whose Even-Degree Vertices Induce a Path are Antimagic
Discussiones Mathematicae Graph Theory, 2022 An antimagic labeling of a connected graph G is a bijection from the set of edges E(G) to {1, 2, . . ., |E(G)|} such that all vertex sums are pairwise distinct, where the vertex sum at vertex v is the sum of the labels assigned to edges incident to v.

A Characterisation of Weak Integer Additive Set-Indexers of Graphs [PDF]
, 2014 An integer additive set-indexer is defined as an injective function $f:V(G)\rightarrow 2^{\mathbb{N}_0}$ such that the induced function $g_f:E(G) \rightarrow 2^{\mathbb{N}_0}$ defined by $g_f (uv) = f(u)+ f(v)$ is also injective.
