k-connected graph


Definition: A connected graph such that deleting any k-1 vertices (and incident edges) results in a graph that is still connected.

See also biconnected graph, triconnected graph, cut vertex.

Note: Informally, there are at least k independent paths from any vertex to any other vertex.
