www2.math.upenn.edu2) The ordering 6is a total well ordering, i.e., the following hold: a) For every n∈N one has: N = {m∈N |m<n}∪{n}∪{m∈N |n<m} In particular, for all m,n∈N one has: Either m6nor n6m. b) If is non-empty, there exists a unique n 0 s.t. nn 0 6n. An consequence of the above is the (generalized) Induction Principle: Theorem 0.4. Let {P n ...

www.personal.psu.eduA statement which is provably equivalent is the well-ordering principle which says that any non-empty set of integers which is bounded below has a minimal element. Theorem 1.1. Every member of N is a product of prime numbers. Proof. 1 is an \empty product" of primes, so the case n= 1 holds. Suppose that we have proved the result for every mwith ...

www2.math.uconn.eduexample, consider the following well known mathematical theorem: Theorem 1 (Euclid). There are in nitely many prime numbers. For those of you who don’t remember, a prime number is a posi-tive integer p>1 that cannot be written as a product of two strictly smaller positive integers aand b. For example, the number 91 is not

A classic representation theorem due to de Finetti (1990) establishes that any collection of ex-changeable random variables has a representation as a mixture distribution—in general an infinite mixture.

Along the way to motivating, formulating precisely and proving this theorem, we will also establish some of the basic facts of Model Theory, Proof Theory and Recursion Theory, three of the main parts of logic. (The fourth is Set Theory.) 1A.
