WebIf a graph has a cutpoint, the connectivity of the graph is 1. The minimum number of points separating two nonadjacent points s and t is also the maximum number of point-disjoint paths between s and t. A bridge is an edge whose removal from a graph increases the number of components (disconnects the graph).

WebAug 6, 2013 · I Googled "graph theory proofs", hoping to get better at doing graph theory proofs, and saw this question. Here was the answer I came up with: Suppose G has m connected components. A vertex in any of those components has at least n/2 neighbors. Each component, therefore, needs at least (n/2 + 1) vertices. In graph theory, a component of an undirected graph is a connected subgraph that is not part of any larger connected subgraph. The components of any graph partition its vertices into disjoint sets, and are the induced subgraphs of those sets. A graph that is itself connected has exactly one component, … See more A component of a given undirected graph may be defined as a connected subgraph that is not part of any larger connected subgraph. For instance, the graph shown in the first illustration has three components. Every … See more It is straightforward to compute the components of a finite graph in linear time (in terms of the numbers of the vertices and edges of the graph) using either breadth-first search or depth-first search.
