About the class of ordered limited operators

We give a brief survey of recent results of order limited operators related to some properties on Banach lattices.

We characterize Banach lattices on which every weak Banach-Saks operator is b-weakly compact.
The lattice copies of in Banach lattices
Marek Wójtowicz (2001)
Commentationes Mathematicae Universitatis Carolinae
Similarity:
It is known that a Banach lattice with order continuous norm contains a copy of if and only if it contains a lattice copy of . The purpose of this note is to present a more direct proof of this useful fact, which extends a similar theorem due to R.C. James for Banach spaces with unconditional bases, and complements the - and -cases considered by Lozanovskii, Mekler and Meyer-Nieberg.

Domination by positive Banach-Saks operators
Julio Flores, César Ruiz (2006)
Studia Mathematica
Similarity:
Given a positive Banach-Saks operator T between two Banach lattices E and F, we give sufficient conditions on E and F in order to ensure that every positive operator dominated by T is Banach-Saks. A counterexample is also given when these conditions are dropped. Moreover, we deduce a characterization of the Banach-Saks property in Banach lattices in terms of disjointness.
Properties of modulus of monotonicity and Opial property in direct sums
Joanna Markowicz, Stanisław Prus (2017)
Annales Universitatis Mariae Curie-Sklodowska, sectio A – Mathematica
Similarity:
We give an example of a Banach lattice with a non-convex modulus of monotonicity, which disproves a claim made in the literature. Results on preservation of the non-strict Opial property and Opial property under passing to general direct sums of Banach spaces are established.

Factorization and domination of positive Banach-Saks operators
Julio Flores, Pedro Tradacete (2008)
Studia Mathematica
Similarity:
It is proved that every positive Banach-Saks operator T: E → F between Banach lattices E and F factors through a Banach lattice with the Banach-Saks property, provided that F has order continuous norm. By means of an example we show that this order continuity condition cannot be removed. In addition, some domination results, in the Dodds-Fremlin sense, are obtained for the class of Banach-Saks operators.
Deviation from weak Banach–Saks property for countable direct sums
Andrzej Kryczka (2014)
Annales Universitatis Mariae Curie-Sklodowska, sectio A – Mathematica
Similarity:
We introduce a seminorm for bounded linear operators between Banach spaces that shows the deviation from the weak Banach–Saks property. We prove that if (Xv) is a sequence of Banach spaces and a Banach sequence lattice E has the Banach–Saks property, then the deviation from the weak Banach–Saks property of an operator of a certain class between direct sums E(Xv) is equal to the supremum of such deviations attained on the coordinates Xv. This is a quantitative version for operators of...
