Main Article Content

Abstract

We focus on the interations of the weighted Berezin transform Tα on Lp(τ), where τ is the invariant measure on the complex unit ball Bn. Iterations of Tα on LR1(τ) the space of radial integrable functions played important roles in proving M-harmonicity of bounded functions with invariant mean value property. Here, we introduce more properties on iterations of Tα on LR1(τ) and observe differences between the iterations of Tα on L1(τ) and Lp(τ) for 1<p<.
