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 the distribution of eigenvalues of the reciprocal distance Laplacian matrix of graphs

S. Pirzada, Saleem Khan

The reciprocal distance Laplacian matrix of a connected graph $G$ is defined as $R D^{L} (G) = R T (G) - R D (G)$ , where $R T (G)$ is the diagonal matrix of reciprocal distance degrees and $RD(G…

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…
