Hamiltonian paths on Platonic graphs

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2004
We develop a combinatorial method to show that the dodecahedron graph has, up to rotation and reflection, a unique Hamiltonian cycle. Platonic graphs with this property are called topologically uniquely Hamiltonian. The same method is used to demonstrate

Energy Conditions for Hamiltonian and Traceable Graphs

open access: yesUniversal Journal of Mathematics and Applications, 2019
A graph is called Hamiltonian (resp. traceable) if the graph has a Hamiltonian cycle (resp. path), a cycle (resp. path) containing all the vertices of the graph. The energy of a graph is defined as the sum of the absolute values of the eigenvalues of the

On Uniquely Hamiltonian Claw-Free and Triangle-Free Graphs

open access: yesDiscussiones Mathematicae Graph Theory, 2015
A graph is uniquely Hamiltonian if it contains exactly one Hamiltonian cycle. In this note, we prove that claw-free graphs with minimum degree at least 3 are not uniquely Hamiltonian.

A closed -knight’s tour on some cylinder chessboards

open access: yesAKCE International Journal of Graphs and Combinatorics, 2020
A -knight’s move on the cylinder chessboard is the move of the knight 2 squares vertically or 2 squares horizontally and then 3 squares perpendicular to it.

Hamiltonian Dynamics in the Theory of Abstraction [PDF]

open access: yes, 2012
This paper deals with fluid flow dynamics which may be Hamiltonian in nature and yet chaotic.Here we deal with sympletic invariance, canonical transformations and stability of such Hamiltonian flows. As a collection of points move along, it carries along

Weakly Dimension-Balanced Hamiltonian Cycle on Three-Dimensional Toroidal Mesh Graph

open access: yesEngineering Proceedings
The dimension-balanced cycle (DBC) problem is new in graph theory, with applications such as 3D stereogram reconstruction. In a graph whose edges are partitioned into k dimensions, a cycle is dimension-balanced if edge counts across dimensions differ by ...

The One-Fault Directed Dimension-Balanced Hamiltonian Problem in Directed Toroidal Mesh Graphs

open access: yesApplied Sciences
Hamiltonian cycle problems play a central role in graph theory and have wide-ranging applications in network-on-chip architectures, interconnection networks, and large-scale parallel systems.
