巴拿赫空间上的自反算子代数

Reflexive Operator Algebras on Banach Spaces

Florence Merlevède, Costel Peligrad, Magda Peligrad

摘要:

本文研究了巴拿赫空间上具有补不变子空间格的有单位强闭算子代数的自反性。我们证明了如果这样的代数包含一个具有有限一致重投影的完备布尔代数,并且具有直和性质,那么它是自反的,即它包含使该代数的不变子空间格中的每个闭子空间保持不变的算子.特别地,这样的代数与它们的双同变子重合。

英文摘要:

In this paper we study the reflexivity of a unital strongly closed algebra of operators with complemented invariant subspace lattice on a Banach space. We prove that if such an algebra contains a complete Boolean algebra of projections of finite uniform multiplicity and with the direct sum property, then it is reflexive, i.e. it contains every operator that leaves invariant every closed subspace in the invariant subspace lattice of the algebra. In particular, such algebras coincide with their bicommutant.
