WebFeb 4, 2024 · Any continuous function of bounded variation which maps each set of measure zero into a set of measure zero is absolutely continuous (this follows, for instance, from the Radon-Nikodym theorem ). Any absolutely continuous function can be represented as the difference of two absolutely continuous non-decreasing functions. WebThe Hahn decomposition theorem states that given a signed measure μ, there exist two measurable sets P and N such that: P ∪ N = X and P ∩ N = ∅; μ ( E) ≥ 0 for each E in Σ such that E ⊆ P — in other words, P is a positive set; μ ( E) ≤ 0 for each E in Σ such that E ⊆ N — that is, N is a negative set. Moreover, this ...
