Spectral Sufficient Conditions on Pancyclic Graphs

open access: yesComplexity, 2021
A pancyclic graph of order n is a graph with cycles of all possible lengths from 3 to n. In fact, it is NP-complete that deciding whether a graph is pancyclic.

Hamilton-Connected Mycielski Graphs∗

open access: yesDiscrete Dynamics in Nature and Society, 2021
Jarnicki, Myrvold, Saltzman, and Wagon conjectured that if G is Hamilton-connected and not K2, then its Mycielski graph μG is Hamilton-connected. In this paper, we confirm that the conjecture is true for three families of graphs: the graphs G with δG>VG ...

Enumeration of the Edge Weights of Symmetrically Designed Graphs

open access: yesJournal of Mathematics, 2021
The idea of super a,0-edge-antimagic labeling of graphs had been introduced by Enomoto et al. in the late nineties. This article addresses super a,0-edge-antimagic labeling of a biparametric family of pancyclic graphs.

Rainbow vertex pair-pancyclicity of strongly edge-colored graphs [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2023
An edge-colored graph is \emph{rainbow }if no two edges of the graph have the same color. An edge-colored graph $G^c$ is called \emph{properly colored} if every two adjacent edges of $G^c$ receive distinct colors in $G^c$.

A Theorem on Even Pancyclic Bipartite Digraphs

open access: yesMathematical Problems of Computer Science, 2021
We prove a Meyniel-type condition and a Bang-Jensen, Gutin and Li-type condition for a strongly connected balanced bipartite digraph to be even pancyclic. Let D be a balanced bipartite digraph of order 2a ≥ 6.

On regular subgraphs of augmented cubes

open access: yesAKCE International Journal of Graphs and Combinatorics, 2020
The n-dimensional augmented cube AQn is a variation of the hypercube It is a -regular and -connected graph on vertices. One of the fundamental properties of AQn is that it is pancyclic, that is, it contains a cycle of every length from 3 to In this paper,

A Note on Cycles in Locally Hamiltonian and Locally Hamilton-Connected Graphs

open access: yesDiscussiones Mathematicae Graph Theory, 2020
Let 𝒫 be a property of a graph. A graph G is said to be locally 𝒫, if the subgraph induced by the open neighbourhood of every vertex in G has property 𝒫. Ryjáček conjectures that every connected, locally connected graph is weakly pancyclic.

Complement of the generalized total graph of fields

open access: yesAKCE International Journal of Graphs and Combinatorics, 2020
Let R be a commutative ring and H be a multiplicative prime subset of R. The generalized total graph is the undirected simple graph with vertex set R and two distinct vertices x and y are adjacent if For a field F, is the only multiplicative prime subset
