Hyperinvariant subspace for absolutely norm attaining and absolutely minimum attaining operators

, 2020
A bounded linear operator $T$ defined on a Hilbert space $H$ is called \textit{norm attaining} if there exist $x\in H$ with unit norm such that $\|Tx\|=\|T\|$.

Approximation in reflexive Banach spaces and applications to the invariant subspace problem [PDF]

, 2004
We formulate a general approximation problem involving reflexive and smooth Banach spaces, and give its explicit solution. Two applications are presented— the first is to the Bounded Completion Problem involving approximation of Hardy class functions ...

Regularity Problem for Extremal Vectors

, 2007
In this paper, we will use results developed by Ansari and Enflo in the theory of bounded linear operators with dense range. We define two maps, with regards to some parameters, that control surjectivity default of a given operator, and prove analycity ...

Descriptive set theoretic methods applied to strictly singular and strictly cosingular operators

, 2008
The class of strictly singular operators originating from the dual of a separable Banach space is written as an increasing union of $\omega_1$ subclasses which are defined using the Schreier sets. A question of J. Diestel, of whether a similar result can
