Toeplitz operators between distinct Bergman spaces

Siyu Wang, Zipeng Wang

For $- 1 < α < \infty$ , let $ω_{α} (z) = (1 + α) (1 - ∣ z ∣^{2})^{α}$ be the standard weight on the unit disk. In this note, we provide descriptions of the boundedness and compactness for the Toeplitz…

Toeplitz operators on weighted Bergman spaces induced by a class of radial weights

Yongjiang Duan, Kunyu Guo, Siyu Wang +1

Suppose that $ω$ is a radial weight on the unit disk that satisfies both forward and reverse doubling conditions. Using Carleson measures and $T 1$ -type conditions, we obtain necess…
