Abstract [en]

We prove an operator inequality for the Bergman shift operator on weighted Bergman spaces of analytic functions in the unit disc with weight function controlled by a curvature parameter α assuming nonnegative integer values. This generalizes results by Shimorin, Hedenmalm and Jakobsson concerning the cases α = 0 and α = 1. A naturally derived scale of Hilbert space operator inequalities is studied and shown to be relaxing as the parameter α > -1 increases. Additional examples are provided in the form of weighted shift operators.
