The descriptive approach to the derivative of a set function with respect to a<i>σ</i>-lattice
This paper contains a definition and a construction of a Radon-Nikodym derivative of a <r-additive set function with respect to a measure on a ^-lattice, that is, a family of sets closed under countable unions and countable intersections.This derivative is characterized in terms of its indefinite integral, and it is …
