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 ${\ell }^p$ for a linear operator $T:E\to X$…
