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). T…
On various diametral notions of points in the unit ball of some vector-valued function spaces
Han Ju Lee, Ãscar 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 GarcÃa, Manuel Maestre, Miguel MartÃn +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…
