**u**be a finite positive regular measure on the Borel sets of a topological space R. Then , for every B - space valued**u**-**measurable**function f on R and every e > 0 there is a Borel set o in R with M ( o ) < ε and such that the ...Page 1221

Thus om is the intersection of a sequence of

Thus om is the intersection of a sequence of

**measurable**sets , and it follows that Om is**u**-**measurable**, completing the proof of statement ( i ) . To complete the proof of the theorem , suppose that the functions Wi ( : , ) , ...Page 1341

Let { Mij } be a positive matrix measure whose elements are continuous with respect to a positive o - finite measure

Let { Mij } be a positive matrix measure whose elements are continuous with respect to a positive o - finite measure
