The word "potentially" … WebIt remains to consider matters for metrizable Stone spaces that are weakly scattered, or equivalently, for countable Boolean algebras that are atomic. The result will depend on whether the Boolean algebra satisfies a stronger form of atomicity. Definition 3.4 For a Boolean algebra B we say a ∈ B is of finite height if [0, a] is finite.
