Extremal distance spectral radius of graphs with $h$ -extra $r$ -component connectivity

Daoxia Zhang, Dan Li, Wenxiu Ding

For two integers $r \geq 2$ and $h \geq 0$ , the $h$ -extra $r$ -component connectivity of a graph $G$ , denoted by $c I^º_{r}^{h}$ , is defined as the minimum number of vertices whose remo…

Extremal distance spectra of graphs and essential connectivity

Daoxia Zhang, Dan Li, Wenxiu Ding

A graph is non-trivial if it contains at least one nonloop edge. The essential connectivity of $G$ , denoted by $I^º^{'} (G)$ , is the minimum number of vertices of $G$ whose removal prod…
