Abstract
- Our aim in this paper is to show that, for any k, there is a finite colouring of the set of rationals whose denominators contain only the first fc primes such that no infinite set has all of its finite sums and products monochromatic. We actually prove a 'uniform' form of this: there is a finite colouring of the rationals with the property that no infinite set whose denominators contain only finitely many primes has all of its finite sums and products monochromatic. We also give various other results, including a new short proof of the old result that there is a finite colouring of the naturals such that no infinite set has all of its pairwise sums and products monochromatic.
