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) +

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

Zero-sum partitions of Abelian groups of order $2^n$ [PDF]
Discrete Mathematics & Theoretical Computer Science, 2023 The following problem has been known since the 80's. Let $\Gamma$ be an Abelian group of order $m$ (denoted $|\Gamma|=m$), and let $t$ and $m_i$, $1 \leq i \leq t$, be positive integers such that $\sum_{i=1}^t m_i=m-1$.

On Local Antimagic Chromatic Number of Cycle-Related Join Graphs
Discussiones Mathematicae Graph Theory, 2021 An edge labeling of a connected graph G = (V, E) is said to be local antimagic if it is a bijection f : E → {1, . . ., |E|} such that for any pair of adjacent vertices x and y, f+(x) ≠ f+(y), where the induced vertex label f+(x) = Σf(e), with e ranging ...

Additive List Coloring of Planar Graphs with Given Girth
Discussiones Mathematicae Graph Theory, 2020 An additive coloring of a graph G is a labeling of the vertices of G from {1, 2, . . . , k} such that two adjacent vertices have distinct sums of labels on their neighbors.

Extension of α‐labelings of quadratic graphs
International Journal of Mathematics and Mathematical Sciences, Volume 2004, Issue 11, Page 571-578, 2004., 2004 First, a new proof for the existence of an α‐labeling of the quadratic graph Q(3, 4k) is presented. Then the existence of α‐labelings of special classes of quadratic graphs with some isomorphic components is shown.

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 ...
