Let \(T\) be the set of all positive integers not in \(S\). By assumption, \(T\) is non-empty. Hence, according to the well-ordering principle, it must contain the smallest element, which we will denote by \(\alpha\).

Webbd) If R is a partial ordering on a set A, B ˆA and a 2A we say that a is an upper bound for B if 8b 2B(bRa_b = a). De nition 2 Let R be a total ordering on a set A. We say that R is a well ordering of A if every nonempty subset X A has an R-least element. We will prove the equivalence, modulo ZF of the following three statements: AC The Axiom ... WebbWe present examples of induction proofs here in hope that they can be used as models when you write your own proofs. These include simple, complete and structural induction. We also present a proof using the Principle of Well-Ordering, and two pretend1 induction proofs. ⋆A Simple InductionProof Problem: Prove that for all natural numbers n>4 ... hydrocephalus epidemiology
