Characterization of the Minimizing Graph of the Connected Graphs Whose Complements Are Bicyclic [PDF]

open access: yesMathematics, 2017
In a certain class of graphs, a graph is called minimizing if the least eigenvalue of its adjacency matrix attains the minimum. A connected graph containing two or three cycles is called a bicyclic graph if its number of edges is equal to its number of ...

Metric Dimensions of Bicyclic Graphs

open access: yesMathematics, 2023
The distance d(va,vb) between two vertices of a simple connected graph G is the length of the shortest path between va and vb. Vertices va,vb of G are considered to be resolved by a vertex v if d(va,v)≠d(vb,v).

The Maximal Total Irregularity of Bicyclic Graphs [PDF]

open access: yesJournal of Applied Mathematics, 2014
In 2012, Abdo and Dimitrov defined the total irregularity of a graph G=(V,E) as irrtG=1/2∑u,v∈VdGu-dGv, where dGu denotes the vertex degree of a vertex u∈V.

On the harmonic index of bicyclic graphs

open access: yesCommunications in Combinatorics and Optimization, 2018
The harmonic index of a graph $G$‎, ‎denoted by $H(G)$‎, ‎is defined as‎ ‎the sum of weights $2/[d(u)+d(v)]$ over all edges $uv$ of $G$‎, ‎where‎ ‎$d(u)$ denotes the degree of a vertex $u$‎. ‎Hu and Zhou [Y‎. ‎Hu and X‎. ‎Zhou‎, ‎WSEAS Trans‎. ‎Math‎. ‎

Computing the Determinant of the Distance Matrix of a Bicyclic Graph

open access: yesElectronic Notes in Theoretical Computer Science, 2019
Abstract Let G be a connected graph with vertex set V = {v1, ..., vn}. The distance d(vi, vj) between two vertices vi and vj is the number of edges of a shortest path linking them. The distance matrix of G is the n × n matrix such that its (i, j)-entry is equal to d(vi, vj).

Bicyclic molecular graphs with the greatest energy [PDF]

open access: yesJournal of the Serbian Chemical Society, 2008
The molecular graph Qn is obtained by attaching hexagons to the end vertices of the path graph Pn-12. Earlier empirical studies indicated that Qn has greatest energy among all bicyclic n-vertex (molecular) graphs.
