Under what conditions is 0 < e s s - s u p p ( d μ d ν I K) < ∞ for every compact subset ∅ ⊂ K ⊆ X. WebbRadon measures. In Section 3 we prove a version of Radon-Nikodym theorem for Radon measures. It di ers from the version in Chapter 5 for now there is a good description of the Radon-Nikodym derivative. As application we deduce Lebsegue-Besicovitch di eren-tiation theorem in Section 4. Next we study the di erentiability properties of functions in R.
