    On the Bishop-Phelps-Bollobás property for numeri9cal radius in C(K) spaces 
    Avilés López, Antonio; Guirao Sánchez, Antonio José; Rodríguez, José (Elsevier, 2014)
    [EN] We study the Bishop-Phelps-Bollobás property for numerical radius within the framework of C(K) spaces. We present several sufficient conditions on a compact space K ensuring that C(K) has the Bishop-Phelps-Bollobás ...

    The numerical index of 2-dimensional Lipschitz-free spaces 
    Cobollo-Gómez, Christian; Guirao Sánchez, Antonio José; Montesinos Santalucia, Vicente (Elsevier, 2024-10-01)
    [EN] We provide the explicit formula for the numerical index of any 2 -dimensional Lipschitz-free space, also giving the construction of operators attaining this value as its numerical radius. As a consequence, the numerical ...
