On the distance Laplacian spectral radius of bicyclic graphs

Linear and Multilinear Algebra, 2021
The distance Laplacian matrix of a connected graph G is defined as L(G)=Tr(G)−D(G), where Tr(G) is the diagonal matrix of the vertex transmissions in G and D(G) is the distance matrix of G.

On the distance spectral radius of digraphs with given diameter

Linear and multilinear algebra, 2019
The distance spectral radius of a strongly connected digraph G is the eigenvalue of its distance matrix with the largest modulus. Let denote the set of strongly connected digraphs with order n and diameter d.

An Aα-spectral radius for a spanning tree with constrained leaf distance in a graph

Filomat
Let ? ? [0, 1) be a real number, and let G be a connected graph of order n with n ? ?(?), where ?(?) = 9 for 0 ? ? ? 2/3 and ?(?) = 4/1?? for 2/3 < ? < 1. A spanning tree T of G is a subgraph of G that is a tree covers all vertices of G.

A NOTE ON THE DISTANCE SPECTRAL RADIUS OF SOME GRAPHS

Discrete Mathematics, Algorithms and Applications, 2014
We characterize graphs with minimal distance spectral radius in two classes of graphs: with vertex connectivity k and minimum degree at least k, and with given number of blocks. Moreover, we determine the unique graph that maximizes the distance spectral radius among all graphs with given clique number.

On the distance spectral radius and the distance energy of graphs

Linear and Multilinear Algebra, 2011
The D-eigenvalues {μ1, μ2, … , μ p } of a connected graph G are the eigenvalues of its distance matrix D. The D-energy of a graph G is the sum of the absolute values of its D-eigenvalues denoted by E D (G). In this article, we obtain a lower bound for the largest D-eigenvalue of G and an upper bound for E D (G) which improve Indulal's bounds [G ...
