N2 - Let D(G),DL(G) = Diag(Tr) − D(G) and DQ(G) = Diag(Tr) + D(G) be, respectively, the distance matrix, the distance Laplacian matrix and the distance signless Laplacian matrix of graph G, where Diag(Tr) denotes the diagonal matrix of the vertex transmissions in G. The eigenvalues of of DL(G) andDQ(G) will be denoted by (Formula presented.) and (Formula presented.), respectively. In this paper, we study the properties of the distance Laplacian eigenvalues and the distance signless Laplacian eigenvalues of graph G.
