On Laplacian and Distance Laplacian Spectra of Generalized Fan Graph & a New Graph Class

Subarsha Banerjee, Soumya Ganguly

Given a graph $G$, the Laplacian matrix of $G$, $L(G)$ is the difference of the adjacency matrix $A(G)$ and $\text{Deg}(G)$, where $\text{Deg}(G)$ is the diagonal matrix of vertex…
