Domination Integrity of Line Splitting Graph and Central Graph of Path, Cycle and Star Graphs [PDF]

open access: yes, 2016
The domination integrity of a connected graph G = (V (G);E(G)) is denoted as DI(G) and defined by DI(G) = min{|S| + m(G - S)}, where S is a dominating set and m(G-S) is the order of a maximum component of G-S. This paper discusses domination integrity of

Seidel spectrum for splitting V-vertex join and S-vertex join of graphs

open access: yesIndonesian Journal of Combinatorics
Splitting V-vertex join and S-vertex join of graphs are the graph structures obtained from splitting graph of a graph. Present work concentrates on the study of Seidel spectrum for the vertex join structures considered.

Some New Results on Various Graph Energies of the Splitting Graph

open access: yesJournal of Chemistry, 2019
The energy of a simple connected graph G is equal to the sum of the absolute value of eigenvalues of the graph G where the eigenvalue of a graph G is the eigenvalue of its adjacency matrix AG.

Investigation of optimized network splitting of large-scale urban centralized heating system operation

open access: yesEnergy Reports, 2020
Operation optimization is a critical issue in the management of the multi-source large-scale urban centralized heating system (UCHS). A major challenge is to deal with the complex topological structure of its heating network. We investigate the operation

On n-connected minors of the es-splitting binary matroids

open access: yesElectronic Journal of Graph Theory and Applications, 2021
The es-splitting operation on an n-connected binary matroid may not yield an n-connected matroid for (n ≥ 3). In this paper, we show that given an n-connected binary matroid M of rank r, the resulting es-splitting binary matroid has an n-connected minor ...

Degree Splitting Graph on Graceful, Felicitous and Elegant Labeling

open access: yes, 2012
Graph labeling methods were introduced by Rosa in 1967 or one given by Graham and Sloane in 1980. For a graph G, the splitting graph S(G) is obtained from G by adding for each vertex v of G, a new vertex v′ so that v′ is adjacent to every vertex in ...

Characterizations for split graphs and unbalanced split graphs

open access: yes, 2021
We introduce a characterization for split graphs by using edge contraction. Then, we use it to prove that any ($2K_{2}$, claw)-free graph with $α(G) \geq 3$ is a split graph. Also, we apply it to characterize any pseudo-split graph. Finally, by using edge contraction again, we characterize unbalanced split graphs which we use to characterize the ...
