Chapter 7 obtains a Beurling–Lax representation for an isometrically included forward-shift-invariant subspace of a weighted Hardy–Fock space which involves a whole family of Bergman-inner-like multipliers (rather than a single inner multiplier) which leads to an orthogonal decomposition of the forward-shift-invariant subspace. The Bergman-inner family can be viewed as the transfer-function family for a time-varying noncommutative, multidimensional weighted-conservative input/state/output linear system, and can be viewed as a time-varying isometric multiplier from a time-varying unweighted Hardy–Fock space to the given weighted Hardy–Fock space.
