which both the 2-vertex- and 2-edge-connectivity of a graph can be easily “read off” The algorithm computes all bridges and cut vertices of the input graph in the

7 sept 2017 · In general a graph is k-connected if the removal of any k − 1 vertices results in a connected graph (c) 2-Edge Connected (a) (b) cut vertex

[PDF] Chapter 5 Connectivity

Similarly, a graph is k-edge connected if it has at least two vertices and no set of k −1 edges is a separator The edge-connectivity of G, denoted by K (G), is the

[PDF] 2-Connected Graphs Definition 1 A graph is connected if for any two

The edge-connectivity of a connected graph G, written κ′(G), is the minimum size of a disconnecting set An edge cut is a set of edges of the form [S, S] for some S

We prove (i) if G is a 2k-edge-connected graph (ka Z), s, t are vertices, and f,, fi, g are edges with f, # g (i = 1, 2), then there exists a cycle C passing through
