Norm attaining operators fromL 1 intoL ∞

Israel Journal of Mathematics, 1998
We show that the set of norm attaining operators is dense in the space of all bounded linear operators fromL 1 intoL ∞.

On a subclass of norm attaining operators

Acta Scientiarum Mathematicarum, 2021
This article is devoted to operators on the Hilbert space which satisfy some properties of norm-attainment. More precisely, a new condition is defined and studied: the authors denote by \(\beta(H)\) the collection of operators \(T\) on the complex Hilbert space \(H\) whose restriction to any reducing subspace \(M\) attains its norm, where \(M\) is ...

Norm attaining operators and James’ Theorem

2001
Abstract There are several results relating isomorphic properties of a Banach space and the set of norm attaining functionals. Here, we show versions for operators of some of these results. For instance, a Banach space X has to be reflexive if it does not contain l1 and for some non trivial Banach space Y and positive r, the unit ball of the space ...

On operators which attain their norm

Israel Journal of Mathematics, 1963
The following problem is considered. LetX andY be Banach spaces. Are those operators fromX toY which attain their norm on the unit cell ofX, norm dense in the space of all operators fromX toY? It is proved that this is always the case ifX is reflexive.

Norm-attaining operators into Lorentz sequence spaces

Proceedings of the Royal Society of Edinburgh: Section A Mathematics, 2009
We prove that the Lorentz sequence spaces do not have the property B of Lindenstrauss. In fact, for any admissible sequences w, v ∈ c0 \ l1, the set of norm-attaining operators from the Orlicz space hϕ(w) (ϕ is a certain Orlicz function) into d(v, 1) is not dense in the corresponding space of operators.
