Group-antimagic Labelings of Multi-cyclic Graphs [PDF]

open access: yesTheory and Applications of Graphs, 2016
Let $A$ be a non-trivial abelian group. A connected simple graph $G = (V, E)$ is $A$-\textbf{antimagic} if there exists an edge labeling $f: E(G) \to A \backslash \{0\}$ such that the induced vertex labeling $f^+: V(G) \to A$, defined by $f^+(v) = \Sigma$

The integer-antimagic spectra of Hamiltonian graphs [PDF]

open access: yesElectronic Journal of Graph Theory and Applications, 2021
Let A be a nontrivial abelian group. A connected simple graph G = (V, E) is A-antimagic, if there exists an edge labeling f : E(G)→A ∖ {0A} such that the induced vertex labeling f+(v)=∑{u, v}∈E(G)f({u, v}) is a one-to-one map.

On d-antimagic labelings of plane graphs

open access: yesElectronic Journal of Graph Theory and Applications, 2013
The paper deals with the problem of labeling the vertices and edges of a plane graph in such a way that the labels of the vertices and edges surrounding that face add up to a weight of that face.

Product Antimagic Labeling of Caterpillars

open access: yesJournal of Mathematics, Volume 2021, Issue 1, 2021., 2021
Let G be a graph with m edges. A product antimagic labeling of G is a bijection from the edge set E(G) to the set {1,2, …, m} such that the vertex‐products are pairwise distinct, where the vertex‐product of a vertex v is the product of labels on the incident edges of v. A graph is called product antimagic if it admits a product antimagic labeling.

On Hamilton‐Connectivity and Detour Index of Certain Families of Convex Polytopes

open access: yesMathematical Problems in Engineering, Volume 2021, Issue 1, 2021., 2021
A convex polytope is the convex hull of a finite set of points in the Euclidean space ℝn. By preserving the adjacency‐incidence relation between vertices of a polytope, its structural graph is constructed. A graph is called Hamilton‐connected if there exists at least one Hamiltonian path between any of its two vertices.

On Antimagic Labeling for Some Families of Graphs

open access: yesIbn Al-Haitham Journal for Pure and Applied Sciences, 2023
Antimagic labeling of a graph  with  vertices and  edges is assigned the labels for its edges by some integers from the set , such that no two edges received the same label, and the weights of vertices of a graph  are pairwise distinct.

Hamilton Connectivity of Convex Polytopes with Applications to Their Detour Index

open access: yesComplexity, Volume 2021, Issue 1, 2021., 2021
A connected graph is called Hamilton‐connected if there exists a Hamiltonian path between any pair of its vertices. Determining whether a graph is Hamilton‐connected is an NP‐complete problem. Hamiltonian and Hamilton‐connected graphs have diverse applications in computer science and electrical engineering.

A Conjecture on Super Edge‐Magic Total Labeling of 4‐Cycle Books

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 2021, Issue 1, 2021., 2021
A graph G is called cycle books B[(4, m), 2] if G consists of m cycles C4 with a common path P2. Figueroa‐Centeno, Ichishima, and Muntaner‐Batle conjecture that the graph B[(4, m), 2] is super edge‐magic total if and only if m is even or m ≡ 5 mod(8). In this article, we prove this conjecture for m ≥ 36 and m = 0 mod (2).

Super H‐Antimagic Total Covering for Generalized Antiprism and Toroidal Octagonal Map

open access: yesJournal of Mathematics, Volume 2021, Issue 1, 2021., 2021
Let G be a graph and H⊆G be subgraph of G. The graph G is said to be (a, d)‐H antimagic total graph if there exists a bijective function f : V(H) ∪ E(H)⟶{1,2,3, …, |V(H)| + |E(H)|} such that, for all subgraphs isomorphic to H, the total H weights W(H) = W(H) = ∑x∈V(H)f(x) + ∑y∈E(H)f(y) forms an arithmetic sequence a, a + d, a + 2d, …, a + (n − 1)d ...

New Perspectives on Classical Meanness of Some Ladder Graphs

open access: yesJournal of Mathematics, Volume 2021, Issue 1, 2021., 2021
In this study, we investigate a new kind of mean labeling of graph. The ladder graph plays an important role in the area of communication networks, coding theory, and transportation engineering. Also, we found interesting new results corresponding to classical mean labeling for some ladder‐related graphs and corona of ladder graphs with suitable ...
