In particular, the results apply to weakly compact operators, Rosenthal operators and Banach–Saks operators.engjournal articlehttps//doi.org/10.1016/j.matpur.2004.01.002http://www.sciencedirect.com/science/article/pii/S0021782404000030restricted access517.518.85Banach-SpacesL1Real InterpolationWeakly Compact OperatorsRosenthal OperatorsBanach-Saks OperatorsMathematicsAppliedAnálisis numérico1206 Análisis Numérico
