A Local Hahn-Banach Theorem and Its Applications

Functional Analysis 2018-09-07 v1

Abstract

An important consequence of the Hahn-Banach Theorem says that on any locally convex Hausdorff topological space XX, there are sufficiently many continuous linear functionals to separate points of XX. In the paper, we establish a `local' version of this theorem. The result is applied to study the uo-dual of a Banach lattice that was recently introduced in [3]. We also provide a simplified approach to the measure-free characterization of uniform integrability established in [8].
