Let $\mathbb{D} = \{z:|z|<1\}$ be open unit disc in complex plane. Define space of analytic function: $N^p=\{f:\mathbb{D} \to \mathbb{C} | f(z)=\sum_{n=0}^{\infty} a_n z^n, \sum_{n=0}^{\infty}|a_n|^p < \infty\}$. For $p=1$ we have Wiener algebra, and for $p=2$ we have Hardy space $H^2$. What we know about this space of analytic function for $p \in (1,2) \cup (2,\infty]$. Describe relationship between Hardy spaces and $N^p$ spaces? Is there any paper or reference for this kind of spaces?

Theory of $H^p$-spaces. However, without further details of what kinds of question you want to answer or investigate, I'm not sure if that book will turn out to be helpful $\endgroup$
