The 6-girth-thickness of the complete graph

open access: yesAKCE International Journal of Graphs and Combinatorics, 2020
The g-girth-thickness of a graph G is the minimum number of planar subgraphs of girth at least g whose union is G. In this paper, we determine the 6-girth-thickness of the complete graph Kn in almost all cases.

Detecting Matching Blunders of Multi-Source Remote Sensing Images via Graph Theory

open access: yesSensors, 2020
Large radiometric and geometric distortion in multi-source images leads to fewer matching points with high matching blunder ratios, and global geometric relationship models between multi-sensor images are inexplicit.

On the bigenus of the complete graphs [PDF]

open access: yesAustralas. J Comb., 2021
We describe an infinite family of edge-decompositions of complete graphs into two graphs, each of which triangulate the same orientable surface. Previously, such decompositions had only been known for only a few complete graphs. These so-called biembeddings solve a generalization of the Earth-Moon problem for an infinite number of orientable surfaces.

A Note on the Geometry of Closed Loops

open access: yesMathematics, 2023
In this paper, we utilize the Ramsey theory to investigate the geometrical characteristics of closed contours. We begin by examining a set of six points arranged on a closed contour and connected as a complete graph. We assign the downward-pointing edges

Dynamic Ramsey Theory of Mechanical Systems Forming a Complete Graph and Vibrations of Cyclic Compounds

open access: yesDynamics, 2023
Ramsey theory constitutes the dynamics of mechanical systems, which may be described as abstract complete graphs. We address a mechanical system which is completely interconnected by two kinds of ideal Hookean springs.

PENGGUNAAN METODE CUTTING PLANE UNTUK MENYELESAIKAN MINIMUM SPANNING TREE DENGAN KENDALA BOBOT PADA GRAF K_n

open access: yesAksioma: Jurnal Program Studi Pendidikan Matematika, 2018
This study aims to determine the minimum spanning tree of a complete graph K_n with weight constraints and completion using the cutting plane method. The cutting plane method is one of the algorithms included in the exact method.

On the Semigroup Whose Elements Are Subgraphs of a Complete Graph

open access: yesMathematics, 2018
Let K n be a complete graph on n vertices. Denote by S K n the set of all subgraphs of K n . For each G , H ∈ S K n , the ring sum of G and H is a graph whose vertex set is V ( G ) ∪ V ( H ) and whose edges are ...
