Let S be an abstract set and E a field ( resp . o - field ) of subsets of S . Let F be an

**additive**( resp . weakly countably**additive**) function on to the set of positiveoperators on a Hilbert space H satisfying F ( 0 ) = 0 and F ( S ) = 1 . Then there

Hence if e , and ex are disjoint then yleq u ez ) = E ( e u ez ) y ( e , u ez ) = [ E ( ez

so that the vector valued set function y is
