Now let the Hilbert space H = { n - 1 Hn be the direct sum of the Hilbert spaces Hn . Elements of H will be denoted by the single letter h . We shall define a map A of X into H. Let D ( A ) = { zt | Enxe D ( An ) for all n and Ë A Enx ...

For each bounded Borel function g on the plane let Š ( g ) denote the closure of AS ( g ) A - 1 . The correspondence q : S ( g ) → Š ( g ) preserves the operational calculus and Q = ssc MĒ ( da ) , boce λΕ ( αλ ) , a where tE ( e ) ...
