Intersection subgroup graph with forbidden subgraphs
Santanu Mandal, Pallabi Manna
Let be a group. The intersection subgroup graph of (introduced by Anderson et al. \cite{anderson}) is the simple graph whose vertices are those non-trivial subgr…
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…
Laplacian eigenvalues and eigenspaces of cographs generated by finite sequence
Santanu Mandal, Ranjit Mehatari, Zoran Stanic
In this paper we consider particular graphs defined by , where is even, is a complete graph o…
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…
