Intersection subgroup graph with forbidden subgraphs

Santanu Mandal, Pallabi Manna

Let $G$ be a group. The intersection subgroup graph of $G$ (introduced by Anderson et al. \cite{anderson}) is the simple graph $Γ_{S} (G)$ 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 $K_{α_{1}} \cup K_{α_{2}} \cup \dots \cup K_{α_{k}}$ , where $k$ is even, $K_{α}$ is a complete graph o…
