• openAccess   Norm-Attaining Tensors and Nuclear Operators 

      Dantas, Sheldon; Jung, Mingu; Roldán, Óscar; Rueda Zoca, Abraham Springer (2022-06)
      Given two Banach spaces X and Y, we introduce and study a concept of norm-attainment in the space of nuclear operators (𝑋�,𝑌�) and in the projective tensor product space 𝑋�⊗ˆ𝜋�𝑌�. We exhibit positive and negative ...
    • openAccess   On norm-attainment in (symmetric) tensor products 

      Dantas, Sheldon; García-Lirola, Luis C.; Jung, Mingu; Rueda Zoca, Abraham Taylor & Francis (2022)
      In this paper, we introduce a concept of norm-attainment in the projective symmetric tensor product of a Banach space X, which turns out to be naturally related to the classical norm-attainment of N -homogeneous polynomials ...
    • openAccess   The Bishop-Phelps-Bollobás properties in complex Hilbert space 

      Choi, Yun Sung; Dantas, Sheldon; Jung, Mingu Wiley (2021-12-02)
      In this paper, we consider theBishop–Phelps–Bollobás point propertyfor variousclasses of operators on complex Hilbert spaces, which is a stronger property thanthe Bishop–Phelps–Bollobás property. We also deal with analogous ...
