WebNov 1, 2024 · 44 3 Borel Functional Calculus Conversely, one can show that to each projection-valued measure E on (K; ) there exists a unique measurable functional calculus E such that E = E E. In the literature, the notation Z K f(z)E(dz) = E(f) (3:3) is used frequently. The reason is that for bounded functions fone has ( (f)xjy) = Z K fd x;y (x;y2H); where Web1 defines a bounded operator x 2 B(H). 2.1.3.
