The ideal property of tensor products of Banach lattices with applications to the local structure of spaces of absolutely summing operators
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.
Let be a locally compact group, and let be a function norm on such that the space of all locally integrable functions with finite -norm is an invariant solid Banach function space. Consider the space of all functions in of which the right translation is a continuous map from into . Characterizations of the case where is a Riesz ideal of are given in terms of the order-continuity of on certain subspaces of . Throughout the paper, the discussion is carried out in the context...
We establish necessary and sufficient conditions under which the linear span of positive AM-compact operators (in the sense of Fremlin) from a Banach lattice into a Banach lattice is an order -complete vector lattice.
Let be a Banach lattice, and denote by its positive cone. The weak topology on is metrizable if and only if it coincides with the strong topology if and only if is Banach-lattice isomorphic to for a set . The weak topology on is metrizable if and only if is Banach-lattice isomorphic to a -space, where is a metrizable compact space.
We characterize Banach lattices on which every positive almost Dunford-Pettis operator is weakly compact.
