The normalized Laplacians and random walks of the parallel subdivision graphs

Jing Zhao, Jia-Bao Liu, Ying-Ying Tan +1

The $k$ -parallel subdivision graph $S_{k} (G)$ is generated from $G$ which each edge of $G$ is replaced by $k$ parallel paths of length 2. The $2 k$ -parallel subdivision graph $S_{2k}(…

A spectral characterization of the $s$ -clique extension of the triangular graphs

Ying-Ying Tan, Jack H. Koolen, Zheng-Jiang Xia

A regular graph is co-edge regular if there exists a constant $μ$ such that any two distinct and non-adjacent vertices have exactly $μ$ common neighbors. In this paper, we show tha…
