B-Multiplier Spaces

Rafael Correa-Morales, Fernando Galaz-Fontes

We develop a general framework for $B$ -multiplier spaces; these are vector spaces $M = M (V, W)$ obtained from a bilinear operator $B : M \times V ⟶ W$ , where $V$ …

Duality between Y-convexity and $Y^{\times}$ -concavity of linear operators between Banach lattices

José Luis Hernández-Barradas, Fernando Galaz-Fontes

In this paper we study the Y-convexity, a property which is obtained by considering a real Banach sequence lattice Y instead of $ℓ^{p}$ for a linear operator $T : E \to X$ …

A generalization of p-convexity and q-concavity on Banach lattices

Fernando Galaz-Fontes, José Luis Hernández-Barradas

In this paper, considering a real Banach sequence lattice Y instead of a Lebesgue sequence space $l_{p}$ we generalize p-convexity of a linear operator $T : E \to X$ , where E is a Banac…

Equivalent Norms in a Banach Function Space and the Subsequence Property

Jose M. Calabuig, Maite Fernández Unzueta, Fernando Galaz-Fontes +1

Given a finite measure space $(Ω, Σ, μ)$ , we show that any Banach space $X (μ)$ consisting of (equivalence classes of) real measurable functions defined on $Ω$ such that $f χ_A \in X(…
