This article is about zero dimension in topology. For several kinds of zero space in algebra, see zero object (algebra).

In mathematics, a zero-dimensional topological space (or nildimensional) is a topological space that has dimension zero with respect to one of several inequivalent notions of assigning a dimension to a given topological space.[1][2]

Definition[edit]

Specifically:

The two notions above agree for separable, metrisable spaces.

Properties of spaces with covering dimension zero[edit]
