On Certain Representations of H∞(G) and the Reflexivity of Associated Operator Algebras

open access: yesJournal of Functional Analysis, 1995
Summary: In [`Normal boundary relations and rationally invariant subspaces', to appear in Integral Equations Oper. Theory], \textit{H. Bercovici} and the second author have proved the existence of rationally invariant subspaces for operators \(T\) admitting as spectral set a compact subset of \(\mathbb{C}\) with nice boundary contained in \(\sigma(T)\).

Generalized derivable mappings at zero point on some reflexive operator algebras

open access: yesLinear Algebra and its Applications, 2005
Let \(L\) be a finite complete commutative subspace lattice on a complex separable Hilbert space \(H\) and let \(\text{alg}(L)\) be the subalgebra of \(B(H)\) (the Banach algebra of all continuous linear operators on \(H\)) consisting of the operators which leave every member of \(L\) invariant.

On the structure of certain reflexive operator algebras

open access: yesJournal of Functional Analysis, 1979
AbstractA characterization is given of the class of operators which commute with the core of a nest algebra modulo its Jacobson radical, and of those projections which commute with every member of the nest algebra modulo its radical. A precise description is given of those operators which commute modulo the radical with every member of the nest algebra
