Zero-dimensional space

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] An illustration of a nildimensional space is a point.[3]

Specifically:

The three notions above agree for separable, metrisable spaces.
