摘要
A new characterization for the boundedness of the difference of composition operators C-phi - C-psi from weighted Bergman spaces into the Bloch space in terms of the Bloch norm of the quantities phi(n) - psi(n), n is an element of N, is given, as well as an asymptotic estimate for the essential norm of the operator.
