Essential Norms of Weighted Composition Operators Between Bloch Type Spaces
MacCluer, Barbara D.; Zhao, Ruhan
We compute the essential norm of a weighted composition operator uC? acting from an analytic Lipschitz space into a weighted Bloch-type space on the disk, and give estimates for the essential norm of uC? when it maps the standard Bloch space into a weighted Bloch-type space. We also study boundedness and compactness of weighted composition operators on analytic Lipschitz spaces from a geometric perspective.

A Volterra Type Operator on Spaces of Analytic Functions
Sisakis, Aristomenis G.; Zhao, Ruhan
The main results are conditions on g such that the Volterra type operator is bounded or compact on BMOA. We also point out certain information when Jg is considered as an operator on a general space X of analytic functions on the disc.

Generalized Schwarz-Pick Estimates
MacCluer, Barbara D.; Stroethoff, Karel; Zhao, Ruhan
We obtain higher derivative generalizations of the Schwarz-Pick inequality for analytic self-maps of the unit disk as a consequence of recent characterizations of boundedness and compactness of weighted composition operators between Bloch-type spaces.
