Induction proof exercises
Web6 mrt. 2024 · Here is the exercise: The proof proceeds by induction. Assume that G is not an abelian group. Let G = k (and p a prime dividing k ), and assume Cauchy's theorem for every group of order less than k. Let C be the center of G, let C a = { x ∈ G; x a x − 1 = a } be the centralizer of a for each a ∈ G, and let k = c + k s + k s + 1 + ⋯ ... Webabout proof by induction that is sometimes missed: Because exercises on proof by induction are chosen to give experience with the inductive step, students frequently assume that the inductive step will be the hard part of the proof. The next example fits this stereotype — the inductive step is the hard part of the proof.
