A connected component is a maximal connected subgraph of an undirected graph. Each vertex belongs to exactly one connected component, as does each edge. A graph is connected if and only if it has exactly one connected component. The strong components are the maximal strongly connected subgraphs of a directed graph. A vertex cut or separating set of a connected graph G is a set of vertices whose removal render… WebGRAPH THEORY { LECTURE 4: TREES 3 Corollary 1.2. If the minimum degree of a graph is at least 2, then that graph must contain a cycle. Proposition 1.3. Every tree on n vertices has exactly n 1 edges. Proof. By induction using Prop 1.1.
