An improved lower bound for the Seidel energy of tree graphs

M. Einollahzadeh, M. A. Nematollahi

Let $G$ be a graph with the 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 $- 1$ i…

Some Mixed Graphs Determined by Their Spectrum

S. Akbari, A. Ghafari, M. Nahvi +1

A mixed graph is obtained from a graph by orienting some of its edges. The Hermitian adjacency matrix of a mixed graph with the vertex set ${v_{1}, \dots, v_{n}}$ , is the mat…
