Exercise 10.5.4: Edge connectivity between two vertices.

Two vertices v and w in a graph G are said to be 2-edge-connected if the removal of any edge in the graph leaves v and w in the same connected component.

(a) Prove that G is 2-edge-connected if every pair of vertices in G are 2-edge-connected.

Let G be a connected simple graph with n vertices and m edges. Prove that G contains at least m−n+ 1 different subgraphs which are polygons (=circuits). Note: Different polygons can have edges in common. For instance, a square with a diagonal edge has three different polygons (the square and two different triangles) even though every pair of polygons have at least one edge in common.

A K-regular graph G is a graph such that deg(v) = K for all vertices v in G. For example, c_9 is a 2-regular graph, because every vertex has degree 2. For some K greater than or equal to 2, neatly draw a simple K-regular graph that has a bridge. If it is impossible, prove why.
