Some improved bounds on two energy-like invariants of some derived graphs

Gui-Xian Tian, Shu-Yu Cui

Given a simple graph $G$ , its Laplacian-energy-like invariant $L E L (G)$ and incidence energy $I E (G)$ are the sum of square root of its all Laplacian eigenvalues and signless Laplaci…

On the Laplacian spectra of some double join operations of graphs

Gui-Xian Tian, Jing-Xiang He, Shu-Yu Cui

Many variants of join operations of graphs have been introduced and their spectral properties have been studied extensively by many researchers. This paper mainly focuses on the La…

On the normalized Laplacian spectra of some subdivision joins of two graphs

Gui-xian Tian, Shu-Yu Cui

For two simple graphs $G_{1}$ and $G_{2}$ , we denote the subdivision-vertex join and subdivision-edge join of $G_{1}$ and $G_{2}$ by $G_{1} \lor ˙ G_{2}$ and $G_{1} ⊻ G_{2}$ , respectively.…
