Stability results for norm attaining operators with range in vector-valued continuous function spaces
Thiago Grando, Elisa R. Santos
In this paper, we prove stability results for the denseness of norm-attaining operators (resp. compact operators), the Bishop-Phelps-Bollobás property for operators (resp. compact…
