The Bishop-Phelps-Bollobás property for the numerical radius: a Zizler-type approach
Sun Kwang Kim, Han Ju Lee, Miguel Martin +1
We investigate the Bishop-Phelps-Bollobás property for the numerical radius (BPBp-nu) through a Zizler-type perspective on the classical Bishop-Phelps-Bollobás property (BPBp). Thi…
On various diametral notions of points in the unit ball of some vector-valued function spaces
Han Ju Lee, Óscar Roldán, Hyung-Joon Tag
In this article, we study the ccs-Daugavet, ccs-, super-Daugavet, super-, Daugavet, , and points in the unit balls of vector-valued function spaces , $…
On density and Bishop-Phelps-Bollobás type properties for the minimum norm
Domingo García, Manuel Maestre, Miguel Martín +2
We study the set of operators between Banach spaces and that attain their minimum norm, and the set of operators that qua…
Linear structures of norm-attaining Lipschitz functions and their complements
Geunsu Choi, Mingu Jung, Han Ju Lee +1
We solve two main questions on linear structures of (non-)norm-attaining Lipschitz functions. First, we show that for every infinite metric space , the set consisting of Lipschi…
On isometric embeddings into the set of strongly norm-attaining Lipschitz functions
Sheldon Dantas, Rubén Medina, Andrés Quilis +1
In this paper, we provide an infinite metric space such that the set $\mbox{SNA}(M)$ of strongly norm-attaining Lipschitz functions does not contain a subspace which is isometr…
On the compact operators case of the Bishop-Phelps-Bollobás property for numerical radius
Domingo Garcia, Manuel Maestre, Miguel Martin +1
We study the Bishop-Phelps-Bollobás property for numerical radius restricted to the case of compact operators (BPBp-nu for compact operators in short). We show that spaces…
Norm attaining operators which satisfy a Bollobás type theorem
Sheldon Dantas, Mingu Jung, Óscar Roldán
In this paper, we are interested in studying the set of all norm-attaining operators from into satisfying the following: given , th…
