Extension problem for quasi-additive set functions and Radon-Nikodym derivatives
Extension problem for quasi-additive set functions and Radon-Nikodym derivatives
Introduction. In the preceding paper [1 ] we have introduced by means of axioms a concept of quasi additive vector-valued set functions +(I) = (41, * * *, Ok) in a class { I} of sets I of a space A, a concept of mesh (D) of certain finite collections …
