Helson Forms and Integral Operators on Bergman Spaces of Dirichlet Series

Tengfei Ma, Yufeng Lu, Chao Zu

We study a family of operators $T_{α}$ , $α > 1$ , on Hilbertian Bergman spaces of Dirichlet series. In the natural orthonormal basis, these operators are represented by weighted multipl…

Nuclear Toeplitz operators between Fock spaces

Tengfei Ma, Yufeng Lu, Chao Zu

We characterize the nuclearity of Toeplitz operators $T_{I^} ¼ : F_{I^} \pm^{p} \to F_{I^} \pm^{q}$ with Borel measure symbols for $1 \leq p, q \leq \infty$ . For positive measures $I^¼$ and $q \leq p$ , we p…
