BibTeX reference

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 DL(G) and DQ(G) will be denoted by L1L2Ln1Ln=0 and Q1Q2Qn1Qn, respectively. In this paper we study the properties of the distance Laplacian eigenvalues and the distance signless Laplacian eigenvalues of graph G.
