On various types of density of numerical radius attaining operators
Sheldon Dantas, Sun Kwang Kim, Han Ju Lee +1
In this paper, we are interested in studying two properties related to the denseness of the operators which attain their numerical radius: the Bishop-Phelps-Bollobás point and oper…
Norm-attaining lattice homomorphisms
Sheldon Dantas, Gonzalo Martínez-Cervantes, José David Rodríguez Abellán +1
In this paper we study the structure of the set $\mbox{Hom}(X,\mathbb{R})$ of all lattice homomorphisms from a Banach lattice into . Using the relation among lattic…
Octahedral norms in free Banach lattices
Sheldon Dantas, Gonzalo Martínez-Cervantes, José David Rodríguez Abellán +1
In this paper, we study octahedral norms in free Banach lattices generated by a Banach space . We prove that if is an -space, a predual of von Neumann algeb…
Norm-attaining tensors and nuclear operators
Sheldon Dantas, Mingu Jung, Óscar Roldán +1
Given two Banach spaces and , we introduce and study a concept of norm-attainment in the space of nuclear operators and in the projective tensor product s…
