Preserved Fulltext
The distance signless Laplacian spectral radius of a connected graph G is the largest eigenvalue of the distance signless Laplacian matrix of G, defined as is the distance matrix of G and T r(G) is the diagonal matrix of vertex transmissions of G. In this paper, we determine some upper and lower bounds on the distance signless Laplacian spectral radius of G based on its order and independence number, and characterize the extremal graphs. In addition, we give an exact description of the distance
