Characterizations of Double Commutant Property on BH
Journal of Function Spaces, 2021 Let H be a complex Hilbert space. Denote by BH the algebra of all bounded linear operators on H. In this paper, we investigate the non-self-adjoint subalgebras of BH of the form T+B, where B is a block-closed bimodule over a masa and T is a subalgebra of

The Structure of Quasinormal Operators and the Double Commutant Property [PDF]
Transactions of the American Mathematical Society, 1982 In this paper a characterization of those quasinormal operators having the double commutant property is obtained. That is, a necessary and sufficient condition is given that a quasinormal operator T T satisfy the equation { T } = A ( T ) \{ T ...

CENTRAL SEQUENCE SUBFACTORS AND DOUBLE COMMUTANT PROPERTIES [PDF]
International Journal of Mathematics, 1999 First, we construct the Jones tower and tunnel of the central sequence subfactor arising from a hyperfinite type II 1 subfactor with finite index and finite depth, and prove each algebra has the double commutant property in the ultraproduct of the enveloping II 1 factor.

On Reflexivity of Certain Hyponormal Operators with Double Commutant Property
Journal of Advances in Mathematics and Computer Science, 2021 Sarason did pioneer work on the reflexivity and purpose of this paper is to discuss the reflexivity of different class of contractions. Among contractions it is now known that C11 contractions with finite defect indices, C.o contractions with unequal defect indices and C1. contractions with at least one finite defect indices are reflexive.
