Graph theory cut edge

WebNov 3, 2024 · Definition. A bond of a graph is a minimal nonempty edge cut; that is, a nonempty edge cut none of whose nonempty proper subsets (of edges) is an edge cut. Note. We can exhaustively check that the bonds of the graph with the given edge cuts in Figure 2.8 are the edge cuts given in Figure 2.11. For example, ∂(u,v) = {vx,vy} is a bond … WebMore generally, an edge cut of G is a set of edges whose removal renders the graph disconnected. The edge-connectivity λ(G) is the size of a smallest edge cut, and the local edge-connectivity λ(u, v) of two vertices u, v is the size of a smallest edge cut disconnecting u from v. Again, local edge-connectivity is symmetric. A graph is called k ...
