Webthe cycles must be even. Therefore, the graph has no odd cycles and is therefore bipartite. 6.Let G 1;:::;G k be the blocks of a simple graph G. Show that ˜(G) = max i=1;:::;k ˜(G i). Solution: By induction on the number kof blocks. The base case with k= 1 is trivial. For the induction step, consider the block-cutpoint graph of G.
