Let M be a σ-finite von Neumann algebra and {σt }t∊T be a σ-weakly continuous representation of the unit circle, T, as *-automorphisms of M. Let H ∞(σ) be the set of all x ∊ M such that

The structure of H ∞(σ) was studied by several authors (see [2-13]).

The main object of this paper is to study the σ-weakly closed subalgebras of M that contain H ∞(σ). In [12] this was done for the special case where H ∞(σ) is a nonselfadjoint crossed product.

Let Mn , for n ∊ Z, be the set of all x ∊ M such that
