Abstract: In this paper, we derive a decomposition formula for spectra of the distance Laplacian matrix DL and distance signless Laplacian matrix DQ of n-Cayley graphs by using group representation theory. Besides, we compute the DL and DQ spectra of the n-gonal n-cone graph and the n-sunlet graph. Finally, we present some examples of DL-integral graphs and DQ-integral graphs.
