Webb3.8 Radon-Nikodym 定理 这一节我们都在测度空间 (X,\mathfrak{a},\mu) 中考虑，其中 \mu 是 带号测度 (signed measure)。 Section 1 绝对连续（absolutely continuous） In mathematics, the Radon–Nikodym theorem is a result in measure theory that expresses the relationship between two measures defined on the same measurable space. A measure is a set function that assigns a consistent magnitude to the measurable subsets of a measurable space. Examples of a … Visa mer Radon–Nikodym theorem The Radon–Nikodym theorem involves a measurable space $${\displaystyle (X,\Sigma )}$$ on which two σ-finite measures are defined, $${\displaystyle \mu }$$ Visa mer This section gives a measure-theoretic proof of the theorem. There is also a functional-analytic proof, using Hilbert space methods, that was first given by von Neumann Visa mer • Let ν, μ, and λ be σ-finite measures on the same measurable space. If ν ≪ λ and μ ≪ λ (ν and μ are both absolutely continuous with respect to λ), then d ( ν + μ ) d λ = d ν d λ + d μ d λ λ … Visa mer Probability theory The theorem is very important in extending the ideas of probability theory from probability masses … Visa mer • Girsanov theorem • Radon–Nikodym set Visa mer Webb(In fact, there is a unique translation invariant Radon measure up to scale by Haar's theorem: the -dimensional Lebesgue measure, denoted here .)
