基于Schauder分解的向量值函数空间的级数表示

Series representations in spaces of vector-valued functions via Schauder decompositions

Karsten Kruse

摘要:

每个$\mathbb{C}$值全纯函数都有局部幂级数表示是一个经典结果。这甚至对值在$\mathbb{C}$上的局部完备局部凸T2空间$E$中的全纯函数也是如此。受这个例子的启发,我们试图回答以下问题。设$E$是域$\mathbb{K}$上的局部凸T2空间,$\mathcal{F}(Ω)$是集合$Ω$上的$\mathbb{K}$值函数的局部凸T2空间,而$\mathcal{F}(Ω,E)$是$\mathcal{F}(Ω)$的$E$值对应(其中项$E$值对应本身需要澄清).对于哪些空间,可以将$\mathcal{F}(Ω)$的元素的级数表示提升为$\mathcal{F}(Ω,E)$的元素?我们推导出充分条件的答案是肯定的,使用Schauder分解是适用于许多经典的空间功能$\mathcal{F}(Ω)$具有等度连续Schauder基础。

英文摘要:

It is a classical result that every $\mathbb{C}$-valued holomorphic function has a local power series representation. This even remains true for holomorphic functions with values in a locally complete locally convex Hausdorff space $E$ over $\mathbb{C}$. Motivated by this example we try to answer the following question. Let $E$ be a locally convex Hausdorff space over a field $\mathbb{K}$, $\mathcal{F}(Ω)$ be a locally convex Hausdorff space of $\mathbb{K}$-valued functions on a set $Ω$ and $\mathcal{F}(Ω,E)$ be an $E$-valued counterpart of $\mathcal{F}(Ω)$ (where the term $E$-valued counterpart needs clarification itself). For which spaces is it possible to lift series representations of elements of $\mathcal{F}(Ω)$ to elements of $\mathcal{F}(Ω,E)$? We derive sufficient conditions for the answer to be affirmative using Schauder decompositions which are applicable for many classical spaces of functions $\mathcal{F}(Ω)$ having an equicontinuous Schauder basis.
