Structure connectivity and substructure connectivity of twisted hypercubes

Dong Li, Xiaolan Hu, Huiqing Liu

Let $G$ be a graph and $T$ a certain connected subgraph of $G$. The $T$-structure connectivity $\kappa (G;T)$ (or resp., $T$-substructure connectivity ${\kappa }^s(G;T)$) of $G$ is the minim…
