• Abstract:
N. Hindman, I. Leader and D. Strauss proved that it is consistent that there is a finite coloring of \mathbb{R} so that no infinite sumset X + X is monochromatic. The (rather fascinating) question if the same conclusion holds in ZFC was open until now: we show that under certain set theoretic assumptions for any c: \mathbb{R} \to r with r finite there is an infinite X \subseteq \mathbb{R} so that C\upharpoonright X + X is constant.
