Vertex energies of splitting and shadow graphs

Harshitha A, Madhumitha K, Sabitha D'Souza

Graph energy has been widely investigated in spectral graph theory. However, the manner in which this energy is distributed among individual vertices has received attention only mo…

On Spectral Properties of Lanzhou Matrix of Graphs

Madhumitha K, Harshitha A, Swati Nayak +1

Let $I^$ be a simple graph on $n$ vertices. Lanzhou index is defined as $L z (I^) = u \in V (I^) \sum d_{I^} (u)^{2} d_{I^} (u) .$ In this manuscript, the Lanzhou matrix, denot…
