Abstract

Let \({\mathcal {H}}\) be a set of connected graphs. A graph is said to be \({\mathcal {H}}\)-free if it does not contain any member of \({\mathcal {H}}\) as an induced subgraph. In this paper, we characterize all pairs RS such that every connected \(\{R,S\}\)-free graph has the same (vertex)-connectivity and edge-connectivity.

Keywords
