High Quality Content by WIKIPEDIA articles! In mathematics, the Radon–Nikodym theorem is a result in functional analysis that states that, given a measurable space (X,?), if a ?-finite measure ? on (X,?) is absolutely continuous with respect to a ?-finite measure ? on (X,?), then there is a measurable function f on X and taking values in [0,?),The function f satisfying the above equality is uniquely defined up to a ?-null set, that is, if g is another function which satisfies the same property, then f = g ?-almost everywhere. f is commonly written d?/d? and is called the Radon–Nikodym derivative. The choice of notation and the name of the function reflects the fact that the function is analogous to a derivative in calculus in the...
