Abstract :

In our previous paper, we had introduced the marker set distance matrix and its eigenvalues. In this paper, we extend them naturally to the Laplacian eigenvalues. To define the Laplacian, we have defined the distance degree sequence of the marker set in the graph. Here we have considered the study of the Laplacian matrix, its characteristic polynomial and related results.

Keywords :

Marker set of a graph, $ M$-set distance matrix, $M$-set distance Laplacian, characteristic polynomial, eigenvalues.
