关于狄利克雷级数的Hardy空间的边界性质及一个框架界估计

On the boundary behaviour of the Hardy spaces of Dirichlet series and a frame bound estimate

Jan-Fredrik Olsen, Eero Saksman

摘要:

普通狄利克雷级数的一类Hardy空间,称为狄利克雷-Hardy空间$\Hp^p$,$p \geq 1$,在Hedenmalm,Lindqvist和Seip在Duke Math.J86(1997),1-37中的一篇论文之后,一直是研究人员越来越感兴趣的焦点。这些空间中的狄利克雷级数收敛于某个半平面上,其中也可以定义经典的Hardy空间$H^p$。本文比较了$\Hp^p$和$H^p$中单元的边界行为。此外,还研究了空间$\Hp^p$的Carleson测度。我们的主要结果表明,对于某些情况,下面的陈述是正确的。给定定义的半平面边界上的一个区间和经典Hardy空间中的一个函数,可以在相应的Dirichlet-Hardy空间中找到一个函数,使得它们的差在这个区间上有一个解析延拓。

英文摘要:

A range of Hardy-like spaces of ordinary Dirichlet series, called the Dirichlet-Hardy spaces $\Hp^p$, $p \geq 1$, have been the focus of increasing interest among researchers following a paper of Hedenmalm, Lindqvist and Seip in Duke Math. J 86 (1997), 1-37. The Dirichlet series in these spaces converge on a certain half-plane, where one may also define the classical Hardy spaces $H^p$. In this paper, we compare the boundary behaviour of elements in $\Hp^p$ and $H^p$. Moreover, Carleson measures of the spaces $\Hp^p$ are studied. Our main result shows that for certain cases the following statement holds true. Given an interval on the boundary of the half-plane of definition and a function in the classical Hardy space, it possible to find a function in the corresponding Dirichlet-Hardy space such that their difference has an analytic continuation across this interval.
