Extremal problems on the $p$ -Seidel energy of graphs

Alexander Guterman, Shib Sankar Saha

Let $G$ be a graph with vertex set ${v_{1}, \dots, v_{n}}$ . The Seidel matrix of $G$ is an $n \times n$ matrix whose diagonal entries are zero, $ij$ -th entry is $- 1$ if $v_{i}$ and $v_{j}$ …

Characterizing uniform hypergraphs via Seidel matrix and Seidel energy

Alexander Guterman, Shib Sankar Saha

The Seidel energy is defined as the sum of the absolute values of the eigenvalues of the Seidel matrix of a hypergraph. We first characterize the k-uniform hypergraphs of fixed ord…

On the Seidel energy of uniform hypergraphs due to hyperedge and vertex deletion

Shib Sankar Saha

Let $S (H)$ be the Seidel matrix of a hypergraph $H$ , and the Seidel energy is denoted by the sum of the absolute eigenvalues of $\mathcal{S}(\mathcal{…
