Abstract

Let ν be a finite countably subadditive outer measure defined on all subsets of a set X, take a collection of subsets of X containing X and , we derive an outer measure ρ using ν on sets in . By applying this general framework on two special cases in which ν=μ, one where μMσ(𝔏) and the other where μMσ(𝔏1),𝔏1𝔏2 being lattices on a set X, we obtain new characterizations of the outer measure μ. These yield useful relationships between various set functions including μi,μj,μ, and μ.
