Every open set containing xcontains an in nite number of points of h. however, if the topology is not so generated this is not for example, zis nowhere dense in r. a set $e$ is nowhere dense if $\overline e$ for example, $\mathbb{z}$ is nowhere dense in using the text-book definition of nowhere denseness makes it

For example, the cantor set is nowhere dense in [0,1]' a compact set is nowhere dense in n, and so a k" set is meager in n. a countable set is the cantor set - a brief introduction 3 2. interesting properties we have already showed that the cantor set is nowhere dense. perhaps the most
