报告摘要:In this talk,under a mild condition, we prove that the vanishing of Berezin type transform on the unit circle is equivalent to the compactness of a class of radial operators on weighted Dirichlet spaces.Futhermore,we characterize the necessary and sufficient condition for Toeplitz operator induced by the bounded radial function to be compact on weighted Dirichlet spaces. We also study the properties of essential commutant of the Toeplitz operator $T_z$.
