On distance Laplacian spread and Wiener index of a graph

Saleem Khan, S. Pirzada

Let $G$ be a simple connected simple graph of order $n$ . The distance Laplacian matrix $D^{L} (G)$ is defined as $D^{L} (G) = D ia g (T r) - D (G)$ , where $D ia g (T r)$ is the diagonal matrix of v…

On Zagreb index, signless Laplacian eigenvalues and signless Laplacian energy of a graph

S. Pirzada, Saleem Khan

Let $G$ be a simple graph with order $n$ and size $m$ . The quantity $M_{1} (G) = i = 1 \sum n d_{v_{i}}^{2}$ is called the first Zagreb index of $G$ , where $d_{v_{i}}$ is the de…

On graphs with distance Laplacian eigenvalues of multiplicity $n - 4$

Saleem Khan, S. Pirzada

Let $G$ be a connected simple graph with $n$ vertices. The distance Laplacian matrix $D^{L} (G)$ is defined as $D^{L} (G) = D ia g (T r) - D (G)$ , where $D ia g (T r)$ is the diagonal matrix of ver…
