Thus if E is a bounded

operators in the B - space X , and if x e X , then the integral s t ( s ) E ( ds ) x is

defined for every bounded E - measurable function f on S. It follows immediately ...

Thus if E is a bounded

**additive**set function on whose values E ( 8 ) are boundedoperators in the B - space X , and if x e X , then the integral s t ( s ) E ( ds ) x is

defined for every bounded E - measurable function f on S. It follows immediately ...

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

operators on a Hilbert space H satisfying F ( $ ) = 0 and F ( S ) = 1 . Then there

exists ...

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

Hence if e , and eg are disjoint then yleq u ez ) = Ele ; u ez ) yle , u ez ) [ E ( e ) +

E ( ez ) ] yle , u ez ) E ( en ) y ( e , u ez ) + E ( ez ) y ( e , vez ) = v ( e ) + v ( eg ) , so

that the vector valued set function y is
