Isometric Composition Operators on for
Zhaopeng Lin
We characterize the analytic self-maps of the unit disk inducing isometric composition operators on \(\BMOA\) with respect to the Möbius-invariant \(H^p\) norm for \(p\ge1\) and th…
Corona theorem for the quaternionic Hardy space
Zhaopeng Lin, Yufeng Lu, Chao Zu
The finite-generator corona theorem for bounded slice regular functions on the quaternionic unit ball was recently established by Colombo, Pozzi, Sabadini, and Wick. In the present…
Slice Regular Composition Operators on Quaternionic Fock Spaces via Matrix Realization
Zhaopeng Lin, Yufeng Lu, Chao Zu
We characterize the boundedness and compactness of slice regular composition operators between quaternionic Fock spaces for the full range \(0<p,q<\infty\), without assuming that t…
A Fourier Criterion for the Toeplitzness of Operators on Fock Spaces
Zhaopeng Lin, Yufeng Lu, Chao Zu
We give a Fourier criterion for the Toeplitzness of bounded operators on Fock spaces, where Toeplitzness means representability as a Toeplitz operator with a bounded measurable sym…
Toeplitz Operators on Quaternionic Fock Spaces
Zhaopeng Lin, Yufeng Lu, Chao Zu
We characterize boundedness and compactness of Toeplitz operators on quaternionic Fock spaces with positive measure symbols and slice-function symbols in \(\mathrm{BMO}^1\). For po…
