WebOct 16, 2024 · 1 Answer. Sorted by: 1. If e is a bridge of G ′, then G ′ − e is disconnected. follows from the definition of a bridge. 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. WebAug 7, 2024 · Graph Theory Connectivity Proof. In this problem, we consider the edge connectivity of a simple undirected graph, which is the minimum number of edges one can remove to disconnect it. Prove that if G is a connected simple undirected graph where every vertex's degree is a multiple of 2, then one must remove at least 2 edges in order …
