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 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…
