Abstract
In this paper, we study how some localized properties, e.g., Dunford–Pettis sets, and \(V^*\)-sets can be used to study more global structure properties. We introduce a new class of Banach spaces called Banach spaces with property \((MB^*)\). We say that a space X has property \((MB^*)\) if every \(V^*\)-set in X is a Dunford–Pettis set in X. We characterize those spaces which have property \((MB^*)\). It is shown that X has property \((MB^*)\) if and only if for every Banach space Y, every unconditionally converging adjoint operator \(T^*\) from \(X^*\) to \(Y^*\) is completely continuous. Also, we recall property (MB) for Banach spaces and then study relation between these two properties.
