Embedding derivatives and derivative Area operators of Hardy spaces into Lebesgue spaces
Xiaosong Liu, Zengjian Lou, Zixing Yuan +1
We characterize the compactness of embedding derivatives from Hardy space into Lebesgue space . We also completely characterize the boundedness and compactness of der…
Some Characterizations for Composition Operators on the Fock Space
Liangying Jiang, Gabriel T. Prajitura, Ruhan Zhao
We study composition operators on the Fock spaces , 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 for any real , 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 , into two weighted Bergman spaces on the unit ball of $\C^n$. To obtain this result, we…
Carleson Measures and Toeplitz operators for weighted Bergman spaces on the unit ball
Jordi Pau, Ruhan Zhao
Some new characterizations on Carleson measures for weighted Bergman spaces on the unit ball involving product of functions are obtained. For these we characterize bounded and comp…
