Conlon and Wu (2022) showed that there is a red/blue-coloring of that does not contain 3 red collinear points separated by unit distance and blue collinear points separated by unit distance. We prove that the statement holds with . We show similar results with different distances between the points.
期刊介绍:
The European Journal of Combinatorics is a high standard, international, bimonthly journal of pure mathematics, specializing in theories arising from combinatorial problems. The journal is primarily open to papers dealing with mathematical structures within combinatorics and/or establishing direct links between combinatorics and other branches of mathematics and the theories of computing. The journal includes full-length research papers on important topics.
