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