摘要: We consider Toeplitz operators with symbol on the Bergman space of the unit ball, and then study the convergences and summability for the sequences of powers of Toeplitz operators. We first charactreize analytic symbols for which the sequence or converges to 0 or as in norm for every nonzero Bergman function . Also, we characterize analytic symbols for which the norm of such a sequence is summable or not summable. We also study the corresponding problems on an infinite direct sum of Bergman spaces as a generalization of our result.
