The vertex-pancyclicity of the simplified shuffle-cube and the vertex-bipancyclicity of the balanced shuffle-cube

Yasong Liu, Huazhong Lü

A graph $G$ $=$ $(V, E)$ is vertex-pancyclic if for every vertex $u$ and any integer $l$ ranging from $3$ to $∣ V ∣$ , $G$ contains a cycle $C$ of length $l$ such that $u$ is on $C$ . A…

On anti-Kekulé and $s$ -restricted matching preclusion problems

Huazhong Lü, Xianyue Li, Heping Zhang

The anti-Kekulé number of a connected graph $G$ is the smallest number of edges whose deletion results in a connected subgraph having no Kekulé structures (perfect matchings). As a…
