ON THE NORM ATTAINING OPERATORS [PDF]

open access: yesKorean Journal of Mathematics, 2012
Summary: In this paper, we show the norm attaining paranormal operators have a nontrivial invariant subspace. Also, we show the norm attaining quadratically hyponormal weighted shift is subnormal.

The Bishop-Phelps-Bollob\'{a}s property for operators on $C(K)$ [PDF]

open access: yes, 2014
We provide a version for operators of the Bishop-Phelps-Bollob\'{a}s Theorem when the domain space is the complex space $C_0(L)$. In fact we prove that the pair $(C_0(L), Y)$ satisfies the Bishop-Phelps-Bollob\'{a}s property for operators for every ...

Bounded holomorphic functions attaining their norms in the bidual [PDF]

open access: yes, 2015
Under certain hypotheses on the Banach space $X$, we prove that the set of analytic functions in $\mathcal{A}_u(X)$ (the algebra of all holomorphic and uniformly continuous functions in the ball of $X$) whose Aron-Berner extensions attain their norms, is

Norm Attaining Operators and Pseudospectrum [PDF]

open access: yesIntegral Equations and Operator Theory, 2009
It is shown that if $11$, the operator $I+T$ attains its norm. A reflexive Banach space $X$ and a bounded rank one operator $T$ on $X$ are constructed such that $\|I+T\|>1$ and $I+T$ does not attain its norm.

Norm Attaining Multilinear Forms on ๐ฟ1(๐)

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2008
Given an arbitrary measure ๐œ‡, this study shows that the set of norm attaining multilinear forms is not dense in the space of all continuous multilinear forms on ๐ฟ1(๐œ‡). However, we have the density if and only if ๐œ‡ is purely atomic. Furthermore, the study

A Lindenstrauss theorem for some classes of multilinear mappings [PDF]

open access: yes, 2015
Under some natural hypotheses, we show that if a multilinear mapping belongs to some Banach multlinear ideal, then it can be approximated by multilinear mappings belonging to the same ideal whose Arens extensions simultaneously attain their norms.

On Norm-Attainable Operators in Banach Spaces [PDF]

open access: yesJournal of Function Spaces, 2020
Norm-attainable operators have been studied over a period of time with nice results obtained particularly in Hilbert spaces. In this work, we consider the Banach space setting by characterizing nonpower operators onHand elementary operators. Lastly, we characterize a new notion of norm-attainability for power operators in general Banach spaces.
