Some results on the energy of the minimum dominating distance signless Laplacian matrix assigned to graphs
Authors
Abstract:
Let G be a simple connected graph. The transmission of any vertex v of a graph G is defined as the sum of distances of a vertex v from all other vertices in a graph G. Then the distance signless Laplacian matrix of G is defined as D^{Q}(G)=D(G)+Tr(G), where D(G) denotes the distance matrix of graphs and Tr(G) is the diagonal matrix of vertex transmissions of G. For a given minimum dominating set of a graph G, our aim in this paper is to define and study the so called minimum dominating distance signless Laplacian matrix, denoted by MDD^{Q}(G). We study some properties of the matrix MDD^{Q}(G). We also define the minimum dominating distance signless Laplacian energy of a graph G, denoted by EDD^{Q}(G), as the sum of the absolute values of the eigenvalues of MDD^{Q}(G), and give some upper and lower bounds for the energy and spectral radius of MDD^{Q}(G).

full textEla on the Least Signless Laplacian Eigenvalue of Some Graphs
For a graph, the least signless Laplacian eigenvalue is the least eigenvalue of its signless Laplacian matrix. This paper investigates how the least signless Laplacian eigenvalue of a graph changes under some perturbations, and minimizes the least signless Laplacian eigenvalue among all the nonbipartite graphs with given matching number and edge cover number, respectively.

For a simple graph $G$, the signless Laplacian Estrada index is defined as $SLEE(G)=sum^{n}_{i=1}e^{q^{}_i}$, where $q^{}_1, q^{}_2, dots, q^{}_n$ are the eigenvalues of the signless Laplacian matrix of $G$.
