摘要

We obtain uniform estimates for the canonical solution to \(\bar{\partial }u=f\) ¯ u = f on the Cartesian product of bounded planar domains with \(C^2\) C 2 boundaries, when f is continuous up to the boundary. This generalizes Landucci’s result for the bidisc toward higher dimensional product domains. In particular, it answers an open question of Kerzman for continuous datum.
