Abstract

We establish various results on norm approximations of bounded linear operators acting on the weighted Bergman space \( {\rm A}_\lambda ^2({\mathbb{B}^n}) \) over the unit ball by means of Toeplitz operators with bounded measurable symbols. The main tool here is the so-called (m, λ)-Berezin transform defined and studied in the paper. In a sense, this is a further development of the ideas and results of [6, 7, 9] to the case of operators acting on \( {\rm A}_\lambda ^2({\mathbb{B}^n}). \)
