On the Laplacian spectrum of $k$ -symmetric graphs

Sunyo Moon, Hyungkee Yoo

For some positive integer $k$ , if the finite cyclic group $Z_{k}$ can act freely on a graph $G$ , then we say that $G$ is $k$ -symmetric. In 1985, Faria showed that the multip…

Sunyo Moon, Seungkook Park

In this paper, we provide an explicit formula for the rank of the walk matrix of the extended Dynkin graph $D ~_{n}$ .
