WebJun 11, 2024 · Your argument would be partially correct but that wouldn't be an induction proof. However we can do one: As you said, for n = 1, it is trivial. Now, suppose inductively it holds for n, i.e. n -cube is bipartite. Then, we can construct an ( n + 1) -cube as follows: Let V ( G n) = { v 1,..., v 2 n } be the vertex set of n -cube. Web6. Show that if every component of a graph is bipartite, then the graph is bipartite. Proof: If the components are divided into sets A1 and B1, A2 and B2, et cetera, then let A= [iAiand B= [iBi. 7.
