Query: Volterra-composition operators on the weighted Bergman space with
  exponential type weights   The properties of Volterra-composition operators on the weighted Bergman
space with exponential type weights are investigated in this paper. We state
some necessary and sufficient conditions that a Volterra-composition operator
from the weighted Bergman space to Bloch type space ( or little Bloch type
space ) must satisfy for the Volterra-composition operator to be bounded or
compact.
