For a Banach space E and its bidual space E'', the function k(H) defined on bounded
subsets H of E measures how far H is from being σ(E,E')-relatively compact in E. This concept, introduced independently by Granero, ...

[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 ...
