MeasureTheory.IsSeparable
Mathlib.MeasureTheory.Measure.SeparableMeasure
{X : Type u_1} → [m : MeasurableSpace X] → MeasureTheory.Measure X → Prop
A measure `μ` is separable if there exists a countable and measure-dense family of sets. The term "separable" is justified by the fact that the definition translates to the usual notion of separability in the metric space made by constant indicators equipped with the `Lᵖ` norm.
