Dunford-Pettis operators on the space of Bochner integrable functions
Let (Ω,Σ,μ) be a finite measure space and let X be a real Banach space. Let be the Orlicz-Bochner space defined by a Young function Φ. We study the relationships between Dunford-Pettis operators T from L¹(X) to a Banach space Y and the compactness properties of the operators T restricted to . In particular, it is shown that if X is a reflexive Banach space, then a bounded linear operator T:L¹(X) → Y is Dunford-Pettis if and only if T restricted to is -compact.
