Dunford-Pettis like Sets with Applications to Spaces of Operators
摘要
Following the concept of L-sets in the dual of a Banach space and using the class of almost Dunford-Pettis sets in a Banach lattice, the notion of L-almost Dunford-Pettis sets is introduced and studied. As an application, Banach lattices with the strong relatively compact Dunford-Pettis property, weak Dunford-Pettis property, and positive Schur property are characterized. Moreover, the behavior of almost Dunford-Pettis completely continuous operators is described and then the domination problem and the adjoint problem for this class of operators are addressed.
