As will be seen in the next section, a normal operator T in Hilbert space ()
determines a spectral measure which is defined on the Boolean algebra 3 of all
Borel sets in the plane and which satisfies (iv) for every 6 e 3. This spectral
measure ...

Let 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 or in R with p(0) < e and such that the restriction of f to the ...
