  • Abstract
    A discretely weak P-set is a nowhere dense closed set which is disjoint from the closure of any countable discrete subset of its complement. We show that the Stone–Čech remainder N ∗ of the discrete space N of natural numbers cannot be covered by discretely weak P-sets when the continuum hypothesis is assumed.
