THE DISTANCE RELATED SPECTRA OF SOME SUBDIVISION RELATED GRAPHS

Journal of Computer Science and Applied Mathematics, 2021
Let $G$ be a connected graph with a distance matrix $D$. The distance eigenvalues of $G$ are the eigenvalues of $D$, and the distance energy $E_D(G)$ is the sum of its absolute values.

Two Laplacians for the resistance distance matrix of a graph

Rendiconti del Circolo Matematico di Palermo Series 2
In this paper, we study the resistance Laplacian and the resistance signless Laplacian matrix associated with a connected graph. We provide the general form of these matrices for various types of graphs, including complete graphs, complete bipartite ...
