Spectra of the neighbourhood corona of two graphs

Xiaogang Liu, Sanming Zhou

Given simple graphs $G_{1}$ and $G_{2}$ , the neighbourhood corona of $G_{1}$ and $G_{2}$ , denoted $G_{1} ⋆ G_{2}$ , is the graph obtained by taking one copy of $G_{1}$ and $∣ V (G_{1}) ∣$ copies of…

Spectral characterizations of propeller graphs

Xiaogang Liu, Sanming Zhou

A propeller graph is obtained from an $\infty$ -graph by attaching a path to the vertex of degree four, where an $\infty$ -graph consists of two cycles with precisely one common vert…

Spectral properties of unitary Cayley graphs of finite commutative rings

Xiaogang Liu, Sanming Zhou

Let $R$ be a finite commutative ring. The unitary Cayley graph of $R$ , denoted $G_{R}$ , is the graph with vertex set $R$ and edge set $a, b : a, b \in R, a - b \in R^{\times}$ , where $R^\t…
