Query: Composition operators acting on weighted Hilbert spaces of analytic
  functions   In this paper, we consider composition operators on weighted Hilbert spaces
of analytic functions and observe that a formula for the essential norm, give a
Hilbert-Schmidt characterization and characterize the membership in
Schatten-class for these operators. Also, closed range composition operators
are investigated.
