If you have a question about this talk, please contact Johannes Carmesin. For a given n, can we colour the positive integers using precisely n colours in such a way that for any a, the numbers a, 2a, .., na all get different colours? This question is still open in general. I will present a survey of known results and some other problems it leads to. This is joint work with Andrés Caicedo and Thomas Chartier. This talk is part of the Combinatorics and Probability seminar series. ## This talk is included in these lists:Note that ex-directory lists are not shown. |
