Enumeration of the Multiplicative Degree-Kirchhoff Index in the Random Polygonal Chains [PDF]

open access: yesMolecules, 2022
Multiplicative degree-Kirchhoff index is a very interesting topological index. In this article, we compute analytical expression for the expected value of the Multiplicative degree-Kirchhoff index in a random polygonal. Based on the result above, we also

Bounds for the Kirchhoff Index of Bipartite Graphs [PDF]

open access: yesJournal of Applied Mathematics, 2012
A -bipartite graph is a bipartite graph such that one bipartition has m vertices and the other bipartition has n vertices. The tree dumbbell consists of the path together with a independent vertices adjacent to one pendent vertex of and b independent ...

Kirchhoff Index and Degree Kirchhoff Index of Tetrahedrane-Derived Compounds

open access: yesSymmetry, 2023
Tetrahedrane-derived compounds consist of n crossed quadrilaterals and possess complex three-dimensional structures with high symmetry and dense spatial arrangements. As a result, these compounds hold great potential for applications in materials science, catalytic chemistry, and other related fields.

Kirchhoff index and degree Kirchhoff index of complete multipartite graphs

open access: yesDiscrete Applied Mathematics, 2017
The Kirchhoff index of a graph is defined as half of the sum of all effective resistance distances between any two vertices. Assuming a complete multipartite graph G, by methods from linear algebra we explicitly formulate effective resistance distances between any two vertices of G, and its Kirchhoff index. In rest of paper we explore extremal value of

Some Bounds for the Kirchhoff Index of Graphs [PDF]

open access: yesAbstract and Applied Analysis, 2014
The resistance distance between two vertices of a connected graph G is defined as the effective resistance between them in the corresponding electrical network constructed from G by replacing each edge of G with a unit resistor.

The Kirchhoff Index of Some Combinatorial Networks [PDF]

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

On lower bounds for the Kirchhoff index [PDF]

open access: yesKragujevac Journal of Science, 2017
Let G be a simple graph of order n ≥ 2 with m edges. Denote by d1 ≥ d2 ≥ · · · ≥ dn > 0 the sequence of vertex degrees and by μ1 ≥ μ2 ≥ · · · ≥ μn−1 > μn = 0 the Laplacian eigenvalues of the graph G. Lower bounds for the Kirchhoff index, Kf(G) = n Σ −1 i=

Research on the Consensus Convergence Rate of Multi-Agent Systems Based on Hermitian Kirchhoff Index Measurement [PDF]

open access: yesEntropy
Multi-agent systems (MAS) typically model interaction topologies using directed or undirected graphs when analyzing consensus convergence rates. However, as system complexity increases, purely directed or undirected networks may be insufficient to ...
