It's an edge whose removal increases the number of components. and κ ( G − e) ≥ k − 1. [I'm using κ for vertex connectivity; this is standard.] This should actually be an upper bound: κ ( G − e) ≤ k − 1.
Bridge of a graph
Did you know?
In graph theory, a bridge, isthmus, cut-edge, or cut arc is an edge of a graph whose deletion increases the graph's number of connected components. Equivalently, an edge is a bridge if and only if it is not contained in any cycle. For a connected graph, a bridge can uniquely determine a cut. A graph is said to be … See more A graph with $${\displaystyle n}$$ nodes can contain at most $${\displaystyle n-1}$$ bridges, since adding additional edges must create a cycle. The graphs with exactly $${\displaystyle n-1}$$ bridges are exactly the See more A bridgeless graph is a graph that does not have any bridges. Equivalent conditions are that each connected component of the graph has an open ear decomposition, … See more • Biconnected component • Cut (graph theory) See more Bridges are closely related to the concept of articulation vertices, vertices that belong to every path between some pair of other vertices.
