Commuting slant Toeplitz operators for polyanalytic and harmonic symbols
Puyu Cui, Ran Li, YuFeng Lu
We study commutativity and zero products of slant Toeplitz operators on the Bergman space of the unit disk. For bounded polyanalytic symbols and for bounded harmonic symbols with b…
Norm of the Hilbert Matrix Operator on Bloch-Type Spaces
Puyu Cui, Zhaopeng Lin, Yufeng Lu
We determine the exact norm of the Hilbert matrix operator on the -Bloch space for , together with all norm-attaining functions of norm one. F…
Spectral properties of Toeplitz operators with harmonic function symbols on the Bergman space
Puyu Cui, Yufeng Lu, Rongwei Yang +1
This paper investigates the spectral properties of Toeplitz operators on the Bergman space of unit disk. We present an integral representation of , which establishes a…
Chaos for Cowen-Douglas operators
Bingzhe Hou, Puyu Cui, Yang Cao
In this article, we provide a sufficient condition which gives Devaney chaos and distributional chaos for Cowen-Douglas operators. In fact, we obtain a distributionally chaotic cri…
