Essential norm of generalized Hilbert matrix from Bloch type spaces to BMOA and Bloch space

Songxiao Li, Jizhen Zhou

Let $μ$ be a positive Borel measure on the interval $[0, 1)$ . The Hankel matrix $H_{μ} = (μ_{n + k})_{n, k \geq 0}$ with entries $μ_{n, k} = μ_{n + k}$ induces the operator $$ \mathcal…

Essential norm and a new characterization of weighted composition operators from weighted Bergman spaces and Hardy spaces into the Bloch space

Songxiao Li, Ruishen Qian, Jizhen Zhou

In this paper, we give some estimates for the essential norm and a new characterization for the boundedness and compactness of weighted composition operators from weighted Bergman…
