To start out with this thought experiment once again, I need to start small. The thought experiment relies on three basic sets of numbers and the idea that each set if written as an infinite sum, can also be written as an infinite product representing the entire set. Secondly, the representation of any single element of each set can be written as an infinite product taken over all prime numbers.
The sets are:
1) The inverse natural numbers
2) The natural numbers
3) The rational numbers
1) The inverse natural numbers: infinite sum = infinite product.
The first set we have already seen. The inverse natural numbers represented as an infinite sum (harmonic series) has an equality that it can also be written as an infinite product.
The Euler product:
and the Euler product with each term of the infinite product expanded as an inverse prime power series
1a) Each individual element of the inverse natural numbers can be written as an infinite product taken over all prime numbers, as:
Where each prime number term has as choices for the its exponent either 0 or a negative integer value.
There is one constraint on an inverse natural number being represented as an infinite product and that is, only finitely many terms of the infinite product can have an exponent choice that is non-zero.
2) The natural numbers: infinite sum = infinite product
The natural numbers represented as an infinite sum has an equality that it can also be written as an infinite product.
2a) The natural numbers - each element can be represented as an infinite product over all prime numbers.
Each individual element of the natural numbers can be written as an infinite product taken over all prime numbers, as:
Where each prime number term has as choices for the its exponent either 0 or a positive integer value.
There is one constraint on a natural number being represented as an infinite product and that is, only finitely many terms of the infinite product can have an exponent choice that is non-zero.
3) The rational numbers - infinite sum = infinite product
The rational numbers represented as an infinite sum has an equality that it can also be written as an infinite product.
3a) The rational numbers - each element can be represented as an infinite product over all prime numbers.
Each individual element of the rational numbers can be written as an infinite product taken over all prime numbers, as:
Where each prime number term has as choices for the its exponent either 0, a positive integer value, or negative integer value.
There is one constraint on a rational number being represented as an infinite product and that is, only finitely many terms of the infinite product can have an exponent choice that is non-zero.
These three basic pieces of information are the starting point for my thought experiment. I think the definitions for
1a,
2a,
3a, are well known. But the representation of the naturals
(2) as an infinite product and the representation of the rationals
(3) as an infinite product may not be. If you know of references for the representation of the naturals
(2) as an infinite product and/or references for the representation of the rationals
(3) as an infinite product, I would like to know them and that they exist, otherwise I will try to show that they are so, from a simple piece of evidence that is a couple of thousand years old.
