Abstract: | Co-authors: Neil Hindman (Howard University), Dona Strauss (University of Leeds)
We show (assuming CH) that there is a finite colouring of the reals such that no infinite set X has X+X (meaning the pairwise sums from X, allowing repetition) monochromatic. And we give positive results for ‘nice’ colourings. |
