The characteristic polynomials of $r$ -uniform hypercycles with length $l$

Dong Bo, Duan Cunxiang, Wang Ligong

Let $C_{l}$ be a cycle with length $l .$ The $r$ -uniform hypercycle with length $l$ is obtained by adding $r - 2$ new vertices in every edge of $C_{l},$ denoted by $C_{l}^{(r)}$ . In thi…

Spectral Properties of Dual Unit Gain Graphs

Chunfeng Cui, Yong Lu, Liqun Qi +1

In this paper, we study dual quaternion and dual complex unit gain graphs and their spectral properties in a unified frame of dual unit gain graphs. Unit dual quaternions represent…
