MeasureTheory.Measure.singularPart

{α : Type u_2} → {m : MeasurableSpace α} → MeasureTheory.Measure α → MeasureTheory.Measure α → MeasureTheory.Measure α

If a pair of measures HaveLebesgueDecomposition, then singularPart chooses the measure from HaveLebesgueDecomposition, otherwise it returns the zero measure. For sigma-finite measures, μ = μ.singularPart ν + ν.withDensity (μ.rnDeriv ν).
