This monograph provides a comprehensive study of a typical and novel function space, known as the $\mathcal{N}_p$ spaces. These spaces are Banach and Hilbert spaces of analytic functions on the open unit disk and open unit ball, and the authors also explore composition operators and weighted composition operators on these spaces. The book covers a significant portion of the recent research on these spaces, making it an invaluable resource for those delving into this rapidly developing area. The authors introduce various weighted spaces, including the classical Hardy space $H^2$, Bergman space $B^2$, and Dirichlet space $\mathcal{D}$. By offering generalized definitions for these spaces, readers are equipped to explore further classes of Banach spaces such as Bloch spaces $\mathcal{B}^p$ and Bergman-type spaces $A^p$. Additionally, the authors extend their analysis beyond the open unit disk $\mathbb{D}$ and open unit ball $\mathbb{B}$ by presenting families of entire functions in the complex plane $\mathbb{C}$ and in higher dimensions. The Theory of $\mathcal{N}_p$ Spaces is an ideal resource for researchers and PhD students studying spaces of analytic functions and operators within these spaces.

"The book is well written and easy to read. Every chapter ends with a short note which gives references for the results. The book provides a useful source for young researchers to gain basic knowledge and various techniques to initiate their own research in the field of operator theory and the theory of spaces of analytic functions." (Ruhan Zhao, Mathematical Reviews, February, 2025)
“The book is pedagogical and detailed. Each chapter ends with a ‘Notes’ section, putting much of the material in historical context, while providing useful additional references. The book is a valuable guide to researchers interested in the topic.” (Amol Sasane, zbMATH 1539.46001, 2024)
