Abstract

Let $D$ be a domain in the complex plane $\mathbb{C}$. The Hardy number of $D$, which first introduced by Hansen, is the maximal number $h(D)$ in $[0,+\infty]$ such that $f$ belongs to the classical Hardy space $H^p (\mathbb{D})$ whenever $00$ and $\alpha>-1$ satisfy $0<\frac{p}{\alpha+2}
平面域的伯格曼数
设$D$是复平面$\mathbb{C}$中的一个域。Hansen首先引入的$D$的Hardy数是$[0,+\infty]$中的最大数$h(D)$,使得$f$属于经典Hardy空间$h^p(\mathbb{D})$,只要$00$和$\alpha>-1$满足$0<\frac{p}{\alpha+2}
