Wiki information Nikodym:
In mathematics, the Radon–Nikodym theorem is a result in measure theory that states that, given a measurable space, if a σ-finite measure ν on is absolutely continuous with respect to a σ-finite measure μ on, then there is a measurable function, such...
Otto Marcin Nikodym was a Polish mathematician. He was educated at the Universities of Lwow and Warsaw, and the Sorbonne. Nikodym taught at the Universities of Kraków and Warsaw and at the Akademia Górnicza in Kraków. He came to the United States in...
