After all, any measurable nonnegative function that integrates to 1 is a density. One major application of the Radon-Nikodym theorem is to prove the existence of the conditional expectation.

Web5 de sept. de 2024 · We call f the Radon-Nikodym (RN) derivative of μ, with respect to m. Proof Note 2. By Definition 3 in §10, we may write " dμ = fdm " for " ∫fdm = μ. " Note 3. Using Definition 2 in §10 and an easy "componentwise" proof, one shows that Theorem 1 holds also with m replaced by a generalized measure s. The formulas μ = ∫fdm and mS(f ≠ h) = 0
