一个局部Hahn-Banach定理及其应用

A Local Hahn-Banach Theorem and Its Applications

Niushan Gao, Denny H. Leung, Foivos Xanthos

摘要:

哈恩-巴拿赫定理的一个重要结论是,在任何局部凸Hausdorff拓扑空间$X$上,有足够多的连续线性泛函来分离$X$的点。在本文中,我们建立了这个定理的“局部”版本。将所得结果应用于文献[3]中引入的巴拿赫格的uo-对偶。我们还提供了一个简化的方法来描述[8]中建立的一致可积性的无测度特征。

英文摘要:

An important consequence of the Hahn-Banach Theorem says that on any locally convex Hausdorff topological space $X$, there are sufficiently many continuous linear functionals to separate points of $X$. 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].
