The Szeged Index of Power Graph of Finite Groups

Subarsha Banerjee

The Szeged index of a graph is an invariant with several applications in chemistry. The power graph of a finite group $G$ is a graph having vertex set as $G$ in which two vertices…

On Structural Properties and Adjacency Spectrum of Coprime Graph of Integers

Subarsha Banerjee

Let $T C G_{n}$ denote the coprime graph having vertex set ${1, 2, \dots, n}$ with any two vertices $i, j$ being adjacent if and only if $g cd (i, j) = 1$ . In this article, we first study s…

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 $Deg (G)$ , where $Deg (G)$ is the diagonal matrix of vertex…
