Spectra of subdivision-vertex and subdivision-edge neighbourhood coronae

Xiaogang Liu, Pengli Lu

Let $G = (V (G), E (G))$ be a graph with vertex set $V (G)$ and edge set $E (G)$ . The subdivision graph $S (G)$ of a graph $G$ is the graph obtained by inserting a new vertex int…

Laplacian spectral characterization of some double starlike trees

Pengli Lu, Xiaogang Liu

A tree is called double starlike if it has exactly two vertices of degree greater than two. Let $H (p, n, q)$ denote the double starlike tree obtained by attaching $p$ pendant vertice…
