Abstract

‎In this paper‎, ‎we study the eigenvalues of the reciprocal distance signless Laplacian matrix of a connected graph and‎

‎obtain some bounds for the maximum‎

‎eigenvalue of this matrix‎. ‎We also focus on bipartite graphs and find some bounds for the spectral radius of the reciprocal distance signless Laplacian matrix of this class of graphs‎. ‎Moreover‎, ‎we give bounds for the reciprocal distance signless Laplacian energy.
