Resumen de A note on a theorem of Zhu on weighted Bergman projections on the polydisc
We show that a holomorphic function in the unit polydisc is the image of a bounded holomorphic function by the weighted Bergman projection if and only if some weighted derivations of the function are bounded. This result improves Theorem 4 in the paper K. Zhu, Weighted Bergman projections on the polydisc
