Operator-weighted composition operators between weighted spaces of vector-valued analytic functions

We investigate several properties of operator-weighted composition maps W-psi,W-phi f (right bar arrow) psi(f o phi) on unweighted H (D, X) and weighted H-nu(infinity) (D, X) spaces of vector-valued analytic functions on the unit disc D. Here phi is an analytic self-map of D and psi is an analytic o...

Description
Summary:We investigate several properties of operator-weighted composition maps W-psi,W-phi f (right bar arrow) psi(f o phi) on unweighted H (D, X) and weighted H-nu(infinity) (D, X) spaces of vector-valued analytic functions on the unit disc D. Here phi is an analytic self-map of D and psi is an analytic operator-valued function on D. We characterize when the operator is continuous, maps a neighbourhood into a bounded set or maps bounded sets into relatively compact sets. In this way we extend results due to Laitila and Tylli for the case of Banach valued functions. This more general setting permits us to compare the results in the unweighted and weighted cases. New examples are provided, especially when the spaces X and Y are Kothe echelon spaces. They show the differences between the present setting and the case of functions taking values in Banach spaces.
