If you have a question about this talk, please contact Andrew Thomason. It is well known that there is a finite colouring of the natural numbers such that there is no infinite set X with X+X (the pairwise sums from X, allowing repetition) monochromatic. It is easy to extend this to the rationals. Hindman, Leader and Strauss showed that there is also such a colouring of the reals, and asked if there exists a space `large enough’ that for every finite colouring there does exist an infinite X with X+X monochromatic. We show that there is indeed such a space. (Joint work with Imre Leader) This talk is part of the Combinatorics Seminar series. ## This talk is included in these lists:- All CMS events
