Composition followed by differentiation between weighted Bergman-Nevanlinna spaces

Ambika Bhat, Zaheer Abbas and Ajay K. Sharma

In this paper, we characterize boundedness of CϕD acting on weighted Bergman-Nevanlinna spaces, where Cϕ is the composition operator and D is the differentiation operator. We also provide a necessary condition and a sufficient condition for CϕD to be compact on weighted BergmanNevanlinna spaces.
