Almost L-Dunford-Pettis sets in Banach lattices and its applications

Abstract: We introduce and study the notion of almost L-Dunford-Pettis sets in Banach lattices and we give some characterizations of it in terms of sequences. As an application, we establish new properties of almost Dunford-Pettis completely continuous operators. Finally, by introducing the concept of aL-Dunford-Pettis property in Banach lattices, we investigate the weak compactness of almost Dunford-Pettis completely continuous operator.

“…The lattice counterpart of this important operator ideal is the class of almost Dunford-Pettis operators: an operator from a Banach lattice to a Banach space is almost Dunford-Pettis if it sends disjoint weakly null sequences to norm null sequences; or, equivalently, if it sends positive disjoint weakly null sequences to norm null sequences. Almost Dunford-Pettis operators have attracted the attention of many experts, for recent developments see [4,5,12,13,18,20,21,22].…”

“…A contrapartida dessa importante classe de operadores no contexto de reticulados de Banach são os operadores quase Dunford-Pettis, que são aqueles que transformam sequências disjuntas fracamente nulas do domínio em sequências nulas em norma no contradomínio. Os operadores lineares quase Dunford-Pettis atraíram a atenção de muitos especialistas, veja por exemplo [8,20,42,48,67,70,71,72].…”
