DIMENSI METRIK PADA GRAF Rn(q; r)m

open access: yesJurnal Matematika UNAND, 2019
The metric dimension of a connected graph G is the cardinality of minimum resolving set in graph G. In this research, how to find the metric dimension of Rn(q; r)m graph. Rn(q; r)m graph is constructing by subdivision operation on Lobster graph Ln(q; r).

On the indices of certain graph products [PDF]

open access: yesTransactions on Combinatorics
Molecular descriptors are numerical graph invariants that are used to study the chemical structure of molecules. In this paper, we determine the upper bound of the Sombor index based on four operations involving the subdivision graph, semi-total point ...

On the Adjacency, Laplacian, and Signless Laplacian Spectrum of Coalescence of Complete Graphs

open access: yesJournal of Mathematics, 2016
Coalescence as one of the operations on a pair of graphs is significant due to its simple form of chromatic polynomial. The adjacency matrix, Laplacian matrix, and signless Laplacian matrix are common matrices usually considered for discussion under ...

Excellent Domination Subdivision Stable Graphs

open access: yesInternational Journal of Basic and Applied Sciences, 2012
Un conjunto de vértices D en un gráfico G = ( V, E ) es un conjunto dominante si cada vértice de V – D es adyacente a algún vértice de D. Si D tiene la cardinalidad más pequeña posible de cualquier conjunto dominante de G, entonces D se llama un conjunto dominante mínimo — abreviado MDS.

Distant Divisor Graph of Subdivision of a Graph

open access: yesInternational Journal of Mathematics and Soft Computing, 2014
Let G = (V;E) be a (p; q) - graph. A shortest path P is called a distant divisor path if l(P) divides q. Distance divisor graphD(G) of a graph G = (V;E) has the vertex set V = V (G) and two vertices in D(G) are adjacent if they have the distant divisor path in G.

几个图运算下的图的惯性指数的界(Bounding the inertia of graphs under some graph operations)

open access: yesZhejiang Daxue xuebao. Lixue ban, 2016
The inertia of a graph G is defined to be the triple In(G) = {i+ (G), i- (G),i0 (G)},where i+ (G),i-(G),i0 (G) are the numbers of positive,negative and zero eigenvalues of the adjacency matrix A(G) including multiplicities, respectively.

The Kirchhoff Index of Some Combinatorial Networks

open access: yesDiscrete Dynamics in Nature and Society, 2015
The Kirchhoff index Kf(G) is the sum of the effective resistance distances between all pairs of vertices in G. The hypercube Qn and the folded hypercube FQn are well known networks due to their perfect properties. The graph G∗, constructed from G, is the

A novel algebraic technique for adjacency matrices of some derived graphs

open access: yesMathematical and Computer Modelling of Dynamical Systems
Graph energy has been the main concern of spectral graph theory in the last five decades. The classical graph energy is the sum of the absolute values of the eigenvalues of the adjacency matrix. In many research papers, different versions of graph energy
