Order boundedness of weighted composition operators on weighted Dirichlet spaces and derivative Hardy spaces

Qingze Lin, Junming Liu, Yutian Wu

In this paper, we completely characterize the order boundedness of weighted composition operators between different weighted Dirichlet spaces and different derivative Hardy spaces.

Volterra type operators on weighted Dirichlet spaces

Qingze Lin

The Carleson measures for weighted Dirichlet spaces had been characterized by Girela and Peláez, who also characterized the boundedness of Volterra type operators between weighted…

Strict singularity of weighted composition operators on derivative Hardy spaces

Qingze Lin, Junming Liu, Yutian Wu

We prove that the weighted composition operator $W_{ϕ, φ}$ fixes an isomorphic copy of $ℓ^{p}$ if the operator $W_{ϕ, φ}$ is not compact on the derivative Hardy space $S^{p}$ . In part…

Strict singularity of Volterra type operators on Hardy spaces

Qingze Lin, Junming Liu, Yutian Wu

In this paper, we first characterize the boundedness and compactness of Volterra type operator $S_{g} f (z) = \int_{0}^{z} f^{'} (ζ) g (ζ) d ζ, z \in D,$ defined on Hardy spaces $H^p, \…
