DESCRIPTION:Title: <a href="https://researchseminars.org/talk/CANT2022/20/
 ">Colouring the smooth numbers</a>\nby Peter Pal Pach (TU Budapest) as par
 t of Combinatorial and additive number theory (CANT 2022)\n\n\nAbstract\nF
 or a given $n$\, can we colour the positive integers using precisely $n$ c
 olours in such a way that for any $a$\, the numbers $a\, 2a\, \\dots\, na$
  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. \n
 \nThis is joint work with Andros Caicedo and Thomas Chartier.\n
