Embeddings of infinite-dimensional spaces in the sets of norm-attaining Lipschitz functions
Geunsu Choi, Mingu Jung, Han Ju Lee +1
Motivated by the result of Dantas et. al. (2023) that there exist metric spaces for which the set of strongly norm-attaining Lipschitz functions does not contain an isometric copy…
Linear structures in the set of non-norm-attaining operators on Banach spaces
Sheldon Dantas, Javier Falcó, Mingu Jung +1
We study large linear structures inside sets arising in the theory of norm-attaining operators. We provide several results in the context of lineability, spaceability, maximal-spac…
The Daugavet and Delta-constants of points in Banach spaces
Geunsu Choi, Mingu Jung
We introduce two new notions called the Daugavet constant and -constant of a point, which measure quantitatively how far the point is from being Daugavet point and -point and…
Rank-one perturbations and norm-attaining operators
Gonzalo Martínez-Cervantes, Mingu Jung, Abraham Rueda Zoca
The main goal of this article is to show that for every (reflexive) infinite-dimensional Banach space there exists a reflexive Banach space and …
