A short note on cospectral and integral chain graphs for Seidel matrix

Santanu Mandal

In this brief communication, we investigate the cospectral as well integral chain graphs for Seidel matrix, a key component to study the structural properties of equiangular lines…

Spectral properties of -graphs

Santanu Mandal, Ranjit Mehatari

Assumed to be undirected, simple, and connected are all of the graphs in this study, and adjacency matrix serves as the associated matrix. In this paper we show that it is poss…

On the spectrum and energy of Seidel matrix for chain graphs

Santanu Mandal, Ranjit Mehatari, Kinkar Chandra Das

We study various spectral properties of the Seidel matrix of a connected chain graph. We prove that is always an eigenvalue of and all other eigenvalues of can hav…

On the Seidel spectrum of threshold graphs

Santanu Mandal, Ranjit Mehatari

In this paper, we analyse spectral properties of Seidel matrix (denoted by ) of connected threshold graphs. We compute the characteristic polynomial and determinant of Seidel ma…
