In the present article, we expose various properties of unbounded absolutely weak Dunford-Pettis and unbounded absolutely weak compact operators on a Banach lattice E . In addition to their topological and lattice properties, we investigate relationships between M -weakly compact operators, L -weakly compact operators, and order weakly compact operators with unbounded absolutely weak Dunford-Pettis operators. We show that the square of any positive uaw -Dunford-Pettis ( M -weakly compact) operator on an order continuous Banach lattice is compact. Many examples are given to illustrate the essential conditions.
Present paper deals with applications of asymptotic equivalence relations on operator nets. These relations are defined via unbounded convergences on vector lattices. Given two convergences c and d on a vector lattice, we study d-asymptotic properties of operator nets formed by c-continuous operators. Asymptotic equivalences are known to be useful and extremely important tools to study infinite behaviors of strongly convergent operator nets and continuous semigroups. After giving a general theory, paper focuses on d-martingale and d-Lotz-Räbiger nets.) is said to be a convergence vector lattice. Let J be an order dense ideal, see [1,2] for more on this notion, in the vector lattice (X, c). Following [5], we write x λwe write uc instead of u J c. Prime examples of c are order convergence and norm convergence which are respectively denoted by o and B Niyazi Anıl Gezer
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
