Abstract

Let D={υC:|υ|<1} be the open unit disk in the complex plane C and let H(D) be the space of all holomorphic functions on  D. For a non-negative integer n and a function fH(D), the nth order differentiation operator is defined as Dnf=f(n). The weighted composition operator together with nth order differentiation operator give rise to a new operator generally termed as generalized weighted composition operator denoted by Wϕ,ξn and is  defined by
Wϕ,ξnf(υ)=ϕ(υ)f(n)(ξ(υ)),fH(D);υD,
where ϕH(D) and ξ is a holomorphic self-map of D. This operator is basically the combination of multiplication operator Mϕ, composition operator  Cξ and nth order differentiation operator Dn. We study the boundedness and compactness of this operator between Dirichlet-type spaces and Bloch-type spaces.
