Volterra type integration operators between weighted Bergman spaces and Hardy spaces

Yongjiang Duan, Siyu Wang, Zipeng Wang

Let $D$ be the class of radial weights on the unit disk which satisfy both forward and reverse doubling conditions. Let $g$ be an analytic function on the unit disk $\mat…

The metric projections onto closed convex cones in a Hilbert space

Yanqi Qiu, Zipeng Wang

We study the metric projection onto the closed convex cone in a real Hilbert space $H$ generated by a sequence $V = {v_{n}}_{n = 0}^{\infty}$ . The first main result…

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…

Hyper-positive definite functions II: A complete study of branching-Toeplitz operators

Yanqi Qiu, Zipeng Wang

We introduce and give a more or less complete study of a family of branching-Toeplitz operators on the Hilbert space $ℓ^{2} (T_{q})$ indexed by a rooted homogeneous tree $T_{q}$ of deg…

Three Remarks on Carleson Measures for Dirichlet Space

Guozheng Cheng, Xiang Fang, Zipeng Wang +1

In this paper, we prove that all doubling measures on the unit disk $D$ are Carleson measures for the standard Dirichlet space $D$ . The proof has three ingredien…

Composition Operators with Quasiconformal Symbols

Xiang Fang, Kunyu Guo, Zipeng Wang

This paper seeks to extend the theory of composition operators on analytic functional Hilbert spaces from analytic symbols to quasiconformal ones. The focus is the boundedness but…
