Bounds on the α-Distance Energy and α-Distance Estrada Index of Graphs

open access: yesDiscrete Dynamics in Nature and Society, 2020
Let G be a simple undirected connected graph, then DαG=αTrG+1−αDG is called the α-distance matrix of G, where α∈0,1, DG is the distance matrix of G, and TrG is the vertex transmission diagonal matrix of G.

Eigenvalues of the resistance-distance matrix of complete multipartite graphs

open access: yesJournal of Inequalities and Applications, 2017
Let G = ( V , E ) $G=(V, E)$ be a simple graph. The resistance distance between i , j ∈ V $i,j\in V$ , denoted by r i j $r_{ij}$ , is defined as the net effective resistance between nodes i and j in the corresponding electrical network constructed from G

Graphs Whose Aα -Spectral Radius Does Not Exceed 2

open access: yesDiscussiones Mathematicae Graph Theory, 2020
Let A(G) and D(G) be the adjacency matrix and the degree matrix of a graph G, respectively. For any real α ∈ [0, 1], we consider Aα (G) = αD(G) + (1 − α)A(G) as a graph matrix, whose largest eigenvalue is called the Aα -spectral radius of G.

Aα-Spectral Characterizations of Some Joins

open access: yesJournal of Mathematics, 2020
Let G be a graph with n vertices. For every real α∈0,1, write AαG for the matrix AαG=αDG+1−αAG, where AG and DG denote the adjacency matrix and the degree matrix of G, respectively.

QUASI-PERMUTATION REPRESENTATIONS OF METACYCLIC 2-GROUPS [PDF]

open access: yesJournal of Sciences, Islamic Republic of Iran, 1998
By a quasi-permutation matrix we mean a square matrix over the complex field C with non-negative integral trace. Thus, every permutation matrix over C is a quasipermutation matrix.

On Minimum Algebraic Connectivity of Tricyclic Graphs [PDF]

open access: yesMathematics Interdisciplinary Research
‎Consider a simple‎, ‎undirected graph $ G=(V,E)$‎, ‎where $A$ represents the adjacency matrix and $Q$ represents the Laplacian matrix of $G$‎. ‎The second smallest eigenvalue of Laplacian matrix of $G$ is called the algebraic connectivity of $G$‎.
