$L^{p} - L^{q}$ boundedness of Forelli-Rudin type operators on the unit ball of $C^{n}$

Ruhan Zhao, Lifang Zhou

We completely characterize $L^{p} - L^{q}$ boundedness of two classes of Forelli-Rudin type operators on the unit ball of $C^{n}$ for all $(p, q) \in [1, \infty] \times [1, \infty]$ …

Some Characterizations for Composition Operators on the Fock Space

Liangying Jiang, Gabriel T. Prajitura, Ruhan Zhao

We study composition operators on the Fock spaces $F_{α}^{2} (C^{n})$ , problems considered include the essential norm, normality, spectra, cyclicity and membership in t…

Weighted BMO and Hankel operators between Bergman spaces

Jordi Pau, Ruhan Zhao, Kehe Zhu

We introduce a family of weighted BMO and VMO spaces for the unit ball and use them to characterize bounded and compact Hankel operators between different Bergman spaces. In partic…

Essential Normality of automorphic composition operators

Liangying Jiang, Caiheng Ouyang, Ruhan Zhao

We first characterize those composition operators that are essentially normal on the weighted Bergman space $A_{s}^{2} (D)$ for any real $s > - 1$ , where induced symbols are automorphisms…

Weak factorization and Hankel forms for weighted Bergman spaces on the unit ball

Jordi Pau, Ruhan Zhao

We establish weak factorizations for a weighted Bergman space $A^p_{\a}$, with $1 < p < \infty$ , into two weighted Bergman spaces on the unit ball of $\C^n$. To obtain this result, we…
