DESCRIPTION:Title: <a href="https://researchseminars.org/talk/CANT2020/3/"
 >Counting subsets avoiding certain multiplicative configurations</a>\nby P
 eter Pal Pach (Budapest University of Technology and Economics) as part of
  Combinatorial and additive number theory (CANT 2021)\n\n\nAbstract\nWe wi
 ll discuss results about enumerating subsets of $\\{1\,2\,\\dots\,n\\}$ av
 oiding certain \nmultiplicative configurations. Namely\, we will count pri
 mitive sets\, $h$-primitive sets \n(where none of the elements divide the 
 product of $h$ other elements) and multiplicative \nSidon sets. Most of th
 ese problems were raised by Cameron and Erdős.\n
