Web2. A k-edges connected graph is disconnected by removing k edges Note that if g is a connected graph we call separation edge of g an edge whose removal disconnects g and separation vertex a vertex whose removal disconnects g. 5.3 Bi-connectivity 5.3.1 Bi-connected graphs Lemma 5.1: Specification of a k-connected graph is a bi-connected … WebThere are 3 types of connectivity when talking about a directed graph G. 1) weakly connected - replacing all of G 's directed edges with undirected edges produces a … In graph theory, a biconnected graph is a connected and "nonseparable" graph, meaning that if any one vertex were to be removed, the graph will remain connected. Therefore a biconnected graph has no articulation vertices. The property of being 2-connected is equivalent to biconnectivity, except that the complete graph of two vertices is usually not regarded as 2-connected. list prime ministers by assumption date
