## 2. 5.7 Connectivity - Graph Theory

Theorem 5.7.5 If G has at least three vertices, then G is 2-connected if and only if every two vertices u and v are contained in a cycle.

We have seen examples of connected graphs and graphs that are not connected. While "not connected'' is pretty much a dead end, there is much to be said about "how connected'' a connected graph is. The simplest approach is to look at how hard it is to disconnect a graph by removing vertices or edges. We assume that all graphs are simple.

Let [math]G = (V, E)[/math] be a given (directed or undirected) graph. The sequence [math]P(u, v)[/math] of edges [math]e_1 = (u, w_1)[/math], [math]e_2 = (w_1, w_2)[/math], …, [math]e_k = (w_{k-1}, v)[/math] is called a "path from the vertex [math]u[/math] to [math]v[/math]. In this case, the vertex [math]v[/math] is reachable from [math]u[/math]. It is assumed that the empty path [math]P(u, u)[/math] leads from [math]u[/math] to itself; that is, each vertex is reachable from itself. A nonempty path [math]P(u, u)[/math] is called a cycle (or a closed walk).
