Web3 / 7 Directionality in Induction In the inductive step of a proof, you need to prove this statement: If P(k) is true, then P(k+1) is true. Typically, in an inductive proof, you'd start off by assuming that P(k) was true, then would proceed to show that P(k+1) must also be true. In practice, it can be easy to inadvertently get this backwards. WebConsider the complete r-partite graph, with each part having n=r vertices. This graph is K r-free, and the total number of edges in this graph is n r 2 r 2 = n2 2 1 1 r. The proof below compares an arbitrary K r+1-free graph with a suitable complete r-partite graph. Proof. We will prove by induction on r that all K r+1-free graphs with the ...
